A series of silylated triarylphosphines was synthesized. Hydrosilylation reactions of styrene with triethoxysilane catalyzed by RhCl 3 /silylated triarylphosphine complexes were investigated. The complexes RhCl 3 /phenylbis(4‐trimethylsilylphenyl)phosphine and RhCl 3 /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.
