We report the first copper(I)‐catalyzed reaction between a disilane and allylic carbonates to produce allylsilanes. The silyl nucleophilic substitution proceeded primarily in a SN2 fashion whereas SN2′ products were also obtained through σ‐π‐σ isomerization of the copper(III) intermediate depending on the substrate’s steric bulk.
我们报告了乙硅烷与烯丙基碳酸酯之间的第一个铜(I)催化反应,生成烯丙基硅烷。甲硅烷基亲核取代主要以S N 2方式进行,而S N 2'产物也通过铜(III)中间体的σ-π-σ异构化而获得,具体取决于底物的空间体积。
