"Bidentale NHC ligands for highly selective homogeneous transition metal-(photo) catalysis"

Abstract : Over the past few decades, direct functionalization of carbon-hydrogen bonds has emerged as a preferred alternative to conventional cross-coupling reactions requiring pre-functionalized substrates. Moreover, photocatalysis offers the possibility to use visible light as a safe, abundant and renewable energy sources.

Based on our expertise in the design of translation metal (TM) catalysts, we have recently developed a new class of N-heterocyclic carbene (NHC) ligands that have demonstrated utility in the preparation of particularly robust Ir(III) photocatalysts, as well as in the development of efficient Rh(III) catalysts for the borylation of C-H bonds.  More recently, we discovered a visible light-induced regioselective C-H functionaliation catalyzed at room temperature by a Rh(I) complex. Following on from this study, Ru(II) and Ir(I) complexes have demonstrated interesting catalytic activites in the regioselective borylation of arylphosphines and in dehydrogenative directed C-H silylation of arenes, respectivity.
