Former Members of the Group

* Melodie Casado Ruano (2014-2019). Dr. Casado carried out a wide research aimed to analyze the effect of the bulky PtBu2 ligand on the stability, structure and reactivity of dimolybdenum cyclopentadienyl complexes having triple intermetallic bonds. This in turn enabled her to study in detail, for the first time, the reactivity of complexes displaying an agostic methyl ligand bridging over a triple intermetallic bond, which led to significant new knowledge and insight concerning dehydrogenation, insertion and elimination processes of alkyl ligands at unsaturated polimetallic centres.

* Estefanía Huergo Iglesias (2013-2018). Dr. Huergo started a new research line in the group, focused on the synthesis and reactivity studies of new complexes having heterometallic multiple bonds. After some studies concerning substrates having MoW triple bonds, she focused her work on systems displaying MoMn and MoRe double bonds, and some derivatives. Particularly interesting rearrangements and bond activation processes were observed in their reactions with p-block molecules having E-H bonds.

* Isabel González Albuerne (2012-2018). Dr. González Albuerne carried out a very extensive research on the reactivity of dimolybdenum complexes bridged by pyramidal phosphinidene ligands, which displayed an extraordinary nucleophilic power. These species were able to react under mild conditions with a great variety of organic molecules to render new phosphorus-donor ligands with novel and sometimes unexpected structures, derived from unprecedented rearrangements in the incoming organic molecule.

* Adrián Toyos Martín (2011-2016). Dr. Toyos carried out a very extensive investigation focused on the search of new binuclear nitrosyl complexes of Mo and W that might be able to induce cleavage or reduction processes at the coordinated NO molecule, and was thus able to synthesize new molecules displaying interesting reactivity, as it is the case of the first unsaturated nitrosyl complex anions (and the corresponding neutral hydrides) or complexes with bridging NO ligands having a substantial pyramidalyzation at their N atoms.

* Raquel Lozano Rivera (2010-2015). Dr. Lozano carried out an extensive study on the chemistry of dimolybdenum complexes bridged by the diphosphorus ligand, particularly in connection with the funcionalization of the white phosphorus molecule, and with their use in the synthesis of heterometallic clusters. Interesting P-P bond cleavage processes were thus unveiled, leading to heterometallic clusters displaying unusual coordination geometries of all these P-donor ligands.

* Belén Alvarez Alijas (2008-2014). Dr. Alvarez Alijas carried out an extensive study on the chemistry of dimolybdenum complexes bridged by multifunctional arylphosphinidene and chalcogenophosphinidene ligands. She discovered interesting functionalization processed invoving these ligands, both at the chalcogen and the metal-bound aryl rings, and the use of these ligands in the synthesis of novel heterometallic clusters supported by phosphinidene and chalcogen ligands.

* Raquel Travieso Puente (2011-2012). During her short stay in the group, Lda. Travieso started studies on the dehydrogenation reactions of amineboranes catalysed by binuclear cyclopentadienyl complexes of the group 6 metals.

* Sonia Menéndez Barrero (2007-2012). Dr. Menéndez carried out a systematic and comprehensive study on the reactivity of neutral and cationic dimolybdenum complexes having bridging benzylidyne ligands and intermetallic bond orders of 2, 2.5 and 3. These reactive species can promote a number of interesting reactions involving the carbyne ligand, these including reversible C-C, P-C and H-C couplings, moreover they are useful intermediates in the synthesis of heterometallic clusters.

* Mª Fernanda Vega González (2007-2011). Dr. Vega carried out an extensive research on the chemistry of ditungsten anions and hydrides having triple intermetallic bonds. Her excellent work proved the dramatic influence that the tungsten atoms have on the reactivity of these unsaturated complexes, when compared to related dimolybdenum species previously studied by the group. There is no doubt: Tungsten makes a difference.

* Jaime Suárez Rivero (2006-2011). Dr. Suárez carried out an extensive and meticulous study on the reactivity of asymmetric dimolybdenum complexes bridged by phosphinidene (PH) or cyclopentadienylidenephosphinidene ligands. He obtained many interesting results, particulary he discovered the multicomponent reactions with alkenes and alkynes.

* Rocío González Alvarez (2005-2010) Dr. Gonzalez carried out a systematic and comprehensive study of the synthesis and reactivity of diiron cyclopentadienyl complexes having pyramidal phosphinidene bridges. These species displayed a strongly nucleophilic behaviour when faced with many different organic molecules and other metal complexes, thereby providing highly selective preparative routes to a huge variety of derivatives having novel organophosphorus ligands, as well as many different heterometallic clusters supported by phosphinidene ligands.

* Mª Eugenia Martínez Galán (2004-2009). Dr. Martinez carried out a systematic study on the protonation reactions of dimolybdenum and ditungsten complexes having bridging dialkyl- or diarylphosphide ligands, these leading in some cases to agostic-like, phosphine bridged derivatives. True agostic, alkyl bridged dimolybdenum complexes were also systematically studied, and in this way several unusual insertion, migration and dehydrogenation processes were uncovered.

* Inmaculada Amor García (2004-2009). Dr. Amor carried out, with a remarkable experimental skill, a detailed and widespread study of the reactivity of asymmetric binuclear complexes having bifunctional phosphinidene bridging ligands, particularly the cyclopentadienylidenephosphinidene ligand. Her work proved the analogy between the chemical behaviour of these ligands and that of the carbene ligands, and even that of the carbyne ligands.

* Daniel García Vivó (2002-present). Dr. García-Vivó carried out a wide experimental study on the chemical behaviour of unsaturated binuclear W and Mo complexes having bridging hydroxycarbyne- and methoxycarbyne ligands. He also performed the first theoretical studies within the group, aimed to better understand the electronic structure of the multiply-bonded dimetal complexes under investigation. Dr. García-Vivó still collaborates with the group on this matter, therefore providing us with very valuable complementary information for a better rationalization of the structure and reactivity of organometallic complexes having multiple intermetallic bonding.

* María Alonso González (2002-2007). Dr. Alonso has been the only member of the group carrying out an investigation focussed on mononuclear complexes. She succeeded in preparing the first anionic oxophosphinidene complexes to be reported in the literature, and this gave her the unique opportunity to explore in detail the chemistry of this rare ligand. Indeed these anions turned to have a high and multipositional reactivity, this leading to a great variety of derivatives, many of them bearing novel and unusual organophosphorus ligands, as shown by the fine experimental work of Dr. Alonso.

* Alberto Ramos Alonso (2001-2016). In his pre-doctoral stage, Dr. Ramos carried out a comprehensive research on the chemistry of anionic and hydride dimolybdenum complexes having triple intermetallic bonds. The multipositional reactivity of these precursors led to the preparation of a great variety of new substances and, equally important, opened new research lines within the group, particularly those related with the chemistry of binuclear species having bridging ligands with agostic C-H and P-H interactions, and the chemistry of neutral and highly unsaturated alkoxycarbyne complexes.

* David Sáez Pérez (2000-2005). Dr. Sáez greatly expanded the chemistry of dimolybdenum and ditungsten cyclopentadienyl complexes having bridging dialkyl- and diarylphosphide ligands, either electron-precise or deficient, neutral and cationic ones. His most important contribution, however, was the discovery of a high-yield preparative route to phosphinidene-bridged complexes, and a preliminary study of their reactivity. This started a new and fruitful research line within the group, still under intense activity.

* Yvonne Anaya Huamán (1999-2003). Dr. Anaya explored in detail the reactivity of dimolybdenum and ditungsten cations having multiple intermetallic bonds, either diamagnetic or paramagnetic ones. She holds the record for the highest formal intermetallic bond order ever achieved in our lab (3.5) in an isolable organometallic complex. Her work was possible thanks to the beneficial effects of the TFPB anion on the corresponding salts of these unsaturated cations (improved solubility, suppression of fluoride transfer and possibility of chromatographic separations).

* Estela Vega Suárez (1998-2002). Dr. Vega has been the only member of the group to undertake an essentially applied research. She succeeded in implementing efficient protocols for the textural and crystallochemical characterization of prilled ammonium nitrate as obtained commercially, and she also carried out a very interesting study on the crystallochemical effects of the commercial surfactants commonly used in the industrial production of the prilled ammonium nitrate.

* Fernanda Cimadevilla González (1998-2002). Dr. Cimadevilla greatly expanded in the group a research line focussed on the chemistry of highly electrophilic binuclear cations having multiple intermetallic bonds. In addition to experiencing the complexities of the reactions of binuclear complexes having several potential protonation sites, Dr. Cimadevilla proved the extraordinary synthetic possibilities of these unsaturated cations by synthesizing a very large number of novel derivatives having a great structural diversity.

* Celedonio Alvarez González (1995-2003). Dr. Alvarez undertook a systematic study on the intramolecular oxidative addition of C-H, P-C, and P-O bonds of coordinated ligands in the binuclear carbonyl complexes of the groups 6 to 8. He greatly developed within the group the chemistry of diiron cyclopentadienyl complexes, with the most relevant contribution being the design of highly efficient procedures for the preparation of phosphide- and phosphinidene-bridged diiron complexes, this being the starting point of extensive further studies.

* Belén Galán de Jove (1995-1996). Dr. Galán was the first member of the group facing the subtleness of diiron cyclopentadienyl complexes. During her short stay in the group she succeeded in unravelling most of the complex reactions taking place in the presence of different bidentate P-donors under photochemical conditions, and involving the cleavage and formation of C-H, P-C and P-O bonds.

* M. Teresa Rueda Lopez (1995-1999). Dr. Rueda pioneered in the group the study of binuclear cyclopentadienyl complexes of the group 6 metals stabilized by bridging dialkyl- and diarylphosphide ligands. She was able to isolate and study the first reasonably stable 33-electron organometallic radicals and also the first 30-electron hydroxycarbyne complexes. Her very careful experimental work led to the preparation of many unusual derivatives that would be the origin of further study by the group.

* Sonia Melón del Amo (1995-1999). Dr. Melón carried out a wide study on the chemistry of binuclear nitrosyl complexes of groups 6 to 8, with particular interest in their potential as catalysts for the decomposition of nitrogen oxides. Her work led to very interesting results concerning the stoichiometric cleavage of the robust N-O bond in the nitrosyl ligand. Perhaps more importantly, her work also provided critical information that later on would be used to initiate a very extensive and fruitful chemistry developed around different anionic and neutral binuclear complexes having triple intermetallic bonds.

* Gemma García Aller (1994-1995). During her short stay in the group, Lda. García focussed her work on the synthesis of unsaturated dimolybdenum cyclopentadienyl complexes by using decarbonylation and chemical oxidation processes as preparative strategies.

* M. Pilar Alvarez Fidalgo (1994-1995). During her short stay in the group, Lda. Alvarez succeeded in clarifying most of the complex aspects of the reactions of unsaturated dimanganese hydrides with organotin hydrides, this requiring a patient and meticulous experimental work.

* Xiang Yang Liu (1991-1995). Dr. Liu carried out a wide and careful experimental study on the reactivity of anionic dimanganese carbonyl compounds, either unsaturated or electron-precise ones. This led to the synthesis of many neutral derivatives, ranging from unusual heterometallic clusters to different binuclear complexes having hydrocarbon ligands following from reorganizations induced by the unsaturated nature of the dimetal centre.

* M. Angeles Alvarez Fidalgo (1990-present). In her pre-doctoral stage Dr. Alvarez pioneered the first studies in the group on ditungsten cyclopentadienyl complexes and discovered the first examples of reversible intramolecular addition of C-H bonds of coordinated cyclopentadienyl ligands. Dr. Alvarez also initiated in the group the first studies on the chemistry of binuclear cations having multiple intermetallic bonds.

* Remedios Carreño García (1986-1992). Dr. Carreño carried out an excellent work focussed on the reactivity of unsaturated dimanganese hydrides towards all sort of molecules having hydrogen-element bonds and several transition-metal complexes. This led to the preparation of a large amount of novel species resulting from the formation of new bonds between the manganese atoms and many p-block and d-block elements.

* Fernando Villafañe Gonzalez (1985-1989). Dr. Villafañe pioneered in the group the study of dimolybdenum cyclopentadienyl complexes. He discovered several interesting bond cleavage processes in the coordinated ligands, particularly the oxidative addition of P-C and P-O bonds. Without his enthusiastic work (most of it carried out under very difficult ambient conditions) much of the ensuing research work carried out by the group would have not been possible.
