Nickel‐catalyzed cross‐coupling reactions of chlorosilanes with organoaluminum reagents were developed. An electron‐rich Ni(0)/PCy3 complex was found to be an effective catalyst for the desired transformation. The reaction of dichlorosilanes 1 proceeded to give the corresponding monosubstituted products 2. Trichlorosilanes 4 underwent selective double substitution to furnish the corresponding monochlorosilanes
开发了镍催化的氯硅烷与有机铝试剂的交叉偶联反应。发现富电子的Ni(0)/ PCy 3络合物是实现所需转化的有效催化剂。进行二氯硅烷1的反应,得到相应的单取代的产物2。对三氯硅烷4进行选择性双取代,以提供相应的一氯硅烷2。总体而言,使用本发明的催化体系可以从二氯和三氯硅烷选择性合成一系列烷基一氯硅烷2。
