Abstract

The direct silylation of 1-alkynes with chlorosilanes smoothly takes place in the presence of zinc powder in acetonitrile, giving good yields of alkynylsilanes. The reactions are tolerant of a wide range of functionalities such as carboxylic acid, ester, alcohol, and chlorine in the 1- alkynes.
