SYNTHESIS OF FUNCTIONALIZED ACYLSILANES FROM CARBOXYLIC-ACID CHLORIDES AND SILYL-ZINC CYANOCUPRATES

The high yielding synthesis of a variety of acylsilanes, most of them unknown and bearing reactive functionalities, has been accomplished by reaction between carboxylic acid chlorides and a novel silyl-zinc cya nocuprate acting as a silyl anion source. The advantages offered by th is procedure with respect to those previously reported, based on carbo xylic acid chlorides or on different starting materials, as well as wi th respect to the use of standard silyl cyanocuprates, are discussed h erein.
