Biographie

Sylviane Sabo-Etienne is CNRS Research Director at the Laboratoire de Chimie de Coordination in Toulouse, France. Her broad research interests encompass coordination chemistry and organometallic chemistry for applications in the fields of energy and catalysis with a specific focus on transition metal complexes displaying H-H, B-H, Si-H, and C-H bonding modes via agostic and/or sigma interactions. Small molecule activation and hydrogen transfer processes are areas under active pursuit with structure-activity relationships, and the mechanism of the catalytic reactions being integral components of the different projects. In the past few years she has received several awards, the most recent being in 2015 "Mme Claude Berthault" award and "Médaille Berthelot" from the French Academy of Science.

Résumé

Polyhydride ruthenium complexes, and particularly those incorporating one or two dihydrogen ligands, are attractive species. The dihydrogen ligand is labile or/and prepares the metal center for hydrogen transfer processes [1]. Activation and functionalization of small molecules are highly desirable as broad applications in the fields of catalysis and energy are expected. Selected recent examples from our group will be detailed with a special focus on mechanistic issues dealing with some important catalytic transformations such as hydrogenation/dehydrogenation reactions, isotopic labeling and CO2 functionalization.
