synthesis of N-aryl or N,N′-diaryl piperazines and trimethylene(bis)piperidines from the corresponding diamines and aryl chlorides using a catalyst combination of Ni(0) associated to 2,2′-bipyridine is described. The Ni/2,2′-bipyridine catalyst is also effective for the sequential arylation of piperazine. The preparation of novel and unsymmetrical 1,4-diaryl piperazines is reported.
描述了使用与2,2'-联吡啶缔合的Ni(0)的催化剂组合,从相应的二胺和芳基氯化物选择性合成N-芳基或N,N'-二芳基哌嗪和三亚甲基(双)哌啶。Ni / 2,2'-联吡啶催化剂对于哌嗪的顺序芳基化也是有效的。报道了新型和不对称的1,4-二芳基哌嗪的制备。
