A nickel/zinc-catalyzed cross-electrophile coupling of alkyl electrophiles activated by an α-cyano group and chlorosilanes is reported. Elemental zinc is the stoichiometric reductant in this reductive coupling process. By this, a C(sp3)−Si bond can be formed starting from two electrophilic reactants whereas previous methods rely on the combination of carbon nucleophiles and silicon electrophiles or
报道了由 α-氰基和氯硅烷活化的烷基亲电试剂在镍/锌催化下的交叉亲电偶联。元素锌是该还原偶联过程中的化学计量还原剂。由此,可以从两种亲电反应物开始形成C(sp 3 )-Si键,而之前的方法依赖于碳亲核试剂和硅亲电试剂的组合,反之亦然。
