Two new catalysts for the dehydrogenative coupling reaction of carboxylic acids with silanes - Convenient methods for an atom-economical preparation of silyl esters
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. Copyright Taylor & Francis Group, LLC.

Triphenylphosphine-catalyzed dehydrogenative coupling reaction of carboxylic acids with silanes - A convenient method for the preparation of silyl esters
Triphenylphosphine has been found to be an efficient catalyst for the dehydrosilylation of carboxylic acids with silanes. In the presence of 4 mol % of triphenylphosphine (PPh3), dehydrosilylation reactions in DMF afforded the corresponding silyl esters at 120 °C in good yield.

Preparation of silyl esters by ZnCl2-catalyzed dehydrogenative cross-coupling of carboxylic acids and silanes
An efficient route to silyl esters by dehydrogenative cross-coupling of silanes and carboxylic acids was investigated. Treatment of silanes and carboxylic acids in the presence of 15mol% of ZnCl2 in DMF at 120 °C afforded the corresponding silyl esters in good yields under relatively mild conditions.
