Abstract

Up to 154-fold rate enhancement (see picture) and higher yields are achieved with the bowl-shaped triarylphosphane ligand P(tm-tp)3 compared with common phosphane ligands in Rh-catalyzed hydrosilylation of ketones. The superior performance of P(tm-tp)3 over the similar P(tp)3 is apparently related to the deeper bowl formed by the methyl-bearing terphenyl substituents in the former.
