Structural variations in acylsilane molecules allow a number of new selective synthetic processes to be performed which lead to sulfur-containing heterocycles, highly functionalized and unsaturated polycarbonyl derivatives, polyenes, and β- and γ-aminoalcohols. The synthesis of these compounds, most of them not easily accessible through conventional routes, takes advantage of the site-selective reactions

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 cyanocuprate acting as a silyl anion source. The advantages offered by this procedure with respect to those previously reported, based on carboxylic aced chlorides or on different starting materials, as well as with respect to the use of standard silyl cyanocuprates, are discussed herein.
