Silylation of 1-alkynes with chlorosilanes promoted by Zn(OTf)2: an efficient way to the preparation of alkynylsilanes

Promoted by Zn(OTf)2, a series of alkynylsilanes were prepared in high yields via direct silylation of terminal alkynes with chlorosilanes under mild conditions. It was supposed that the reaction was through the intermediate of Zn alkynilide.
