Abstract

Abstract Tris (triphenylphosphine) cuprous chloride [Cu (PPh3) 3Cl] has been found to be an efficient catalyst for the dehydrosilylation of carboxylic acids with silanes. In the presence of 4 mol% Cu (PPh3) 3Cl, dehydrosilylation reactions in acetonitrile afforded the corresponding silyl esters at 80° C in good yields. It was noted that triphenylphosphine itself also functions as an adequate catalyst for the reaction.
