We have demonstrated that a cooperative catalytic system comprised of CuCl and Cu(OTf)2 could be used to effectively catalyse the three-, five- and seven-component coupling reactions of aliphatic or aromatic amines, formaldehyde, and trimethylsilyl cyanide (TMSCN), and selectively produce in good yields the corresponding cyanomethylamines, N,N-bis(cyanomethyl)amines and N,N'-bis(cyanomethyl)methylenediamines.
我们已经证明,由CuCl和Cu(OTf)2组成的协同催化系统可以有效催化脂肪族或芳香族胺、甲醛和三甲基硅基氰化物(TMSCN)的三元、五元和七元偶联反应,并选择性地以良好的产率生成相应的氰甲基胺、N,N-双(氰甲基)胺和N,N'-双(氰甲基)亚甲基二胺。
