Iridium() complexes with bidentate NHC ligands as catalysts for dehydrogenative directed C-H silylation

A series of (NHC)(cod)Ir( i ) complexes bearing NHC-carboxylate ligands were efficiently synthesized and fully characterized. Their solid-state structures confirmed the bidentate coordination mode of these LX-type NHC ligands. These unprecedented iridium( i ) complexes demonstrated efficient catalyt...

Description
Summary:A series of (NHC)(cod)Ir( i ) complexes bearing NHC-carboxylate ligands were efficiently synthesized and fully characterized. Their solid-state structures confirmed the bidentate coordination mode of these LX-type NHC ligands. These unprecedented iridium( i ) complexes demonstrated efficient catalytic activities in dehydrogenative directed C-H silylation of arenes, and allowed for excellent ortho -selectivity control with aromatic silylating agents. Bidentate NHC-Ir( i ) catalysts for selective dehydrogenative C-H silylation.
