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.
在β-三苯基甲硅烷基烯丙醇与叔丁醇铜(I)和烯丙基卤化物的反应中,烯丙基取代了乙烯基硅烷中的硅基。该反应是首次应用于1,3 Csp2-到-O硅基迁移的合成应用,提供了一种生成乙烯基阴离子等效物的有用方法。
