Ruthenium Catalyzed Selective Deacryloyl Silylation of Aromatic Acrylates

Abstract

An efficient and highly selective ruthenium-catalyzed deacryloyl silylation of aromatic acrylates is presented. A diverse range of monosilyl-ethers and disilyl-ethers were readily synthesized with excellent functional group compatibility, affording moderate to high yields under mild reaction conditions using hydrosilanes and aromatic acrylates as substrates. The ruthenium catalytic system demonstrated remarkable chemo-and regio-selectivity. Moreover, a gram-scale synthesis was successfully achieved, and a plausible reaction mechanism involving the deacryloyl process was proposed.
