Ernesto Carmona

He is PhD degree, University of Seville, 1974, Professor F. González García, and did postdoctoral work at Imperial College London with (the late) Professor Sir Geoffrey Wilkinson (1974-1977). He then returned to Sevilla, to become full Professor in 1983, where he established an independent research group in the area of Organometallic Chemistry.

Over the years, his research interests have concentrated in the activation of small, unsaturated molecules, like N2, CO, CO2, C2H4, etc., by compounds of several transition elements, in particular by low-valent molybdenum and tungsten compounds containing phosphine ligands, and also by organometallic compounds of nickel and palladium.

During the last 15 years his group has studied the capacity of Tp’Rh and Tp’Ir complexes (Tp’= hydrotris(pyrazolyl)borate ligand) to induce the activation of C-H bonds (to a lesser extent C-O and C-N bonds), and also to achieve the selective formation of C-C bonds. Recent work has demonstrated that unsaturated Tp’Ir(III) fragments are capable to effect the selective rupture of the Calkyl-O bond of alkyl aryl ethers, ROAr, in tandem reactions that imply multiple C-H bond activation, C-O cleavage and C-C bond formation. Moreover, these complexes are also capable to promote tautomerization of 2-substituted pyridines, and even of unsubstituted pyridine, to corresponding N-heterocyclic carbenes.

More recently his group has studied the structural characteristics of metallocenes of actinide and main group elements. Investigations on zinc cyclopentadienyls permitted the characterization of different zincocenes, among them the first molecular compound of zinc that contains a Zn-Zn bond. This discovery has opened the way to the preparation of other compounds of the [Zn-Zn]2+ unit and to the development of this new area of zinc chemistry. His interest in metal-metal bonded complexes has extended recently to encompass multiply bonded dimolybdenum and ditungsten compounds, in particular methyl, hydride and other complexes of molybdenum with quadruple or quintuple metal-metal bonds. Current research includes also the study of late transition metal complexes with bulky terphenyl phosphine ligands and their applications in some homogenous catalytic reactions.
