The substitution of the silyl group in vinylsilanes by an allylic group proceeded when β-triphenylsilylallyl alcohols were treated with copper(I) tert-butoxide and allylic halides. This reaction is the first synthetic application of 1,3 Csp2-to-O silyl migration which provides a useful method for generation of vinyl anion equivalents.
