Effect of Silylated Triarylphosphine Ligands on Rhodium‐catalyzed Hydrosilylation
Applied organometallic chemistry（2016）
Abstract
A series of silylated triarylphosphines was synthesized. Hydrosilylation reactions of styrene with triethoxysilane catalyzed by RhCl3/silylated triarylphosphine complexes were investigated. The complexes RhCl3/phenylbis(4‐trimethylsilylphenyl)phosphine and RhCl3/tris(4‐trimethylsilylphenyl)phosphine exhibited higher activity as well as greater β‐adduct selectivity, and no unsaturated product was obtained. The results suggest that the silyl moieties have a significant impact on the catalytic process. Copyright © 2016 John Wiley & Sons, Ltd.
