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.
