This invention provides a process for preparing aminoarylacetylenes comprising reacting a N-arylmethylidene aminoarylhalide with a terminal acetylene in the presence of a base and a catalyst system comprising a palladium catalyst and a cuprous salt to produce a novel N-arylmethylidene aminoarylacetylene, and hydrolyzing the N-arylmethylidene aminoarylacetylene to the aminoarylacetylene. In one embodiment, the invention provides a process for preparing aminophenylacetylenes comprising reacting a N-benzylidene aminophenylhalide with a terminal acetylene in the presence of a base and the catalyst system to produce a novel N-benzylidene aminophenylacetylene, and hydrolyzing the N-benzylidene aminophenylacetylene to the aminophenylacetylene .
(ZH) 本发明提供了一种制备氨基芳基炔的方法,该方法包括:在碱和包括钯催化剂与亚铜盐的催化剂体系的存在下,将N－芳亚甲基氨基芳基卤与末端炔反应,生成一种新型N－芳亚甲基氨基芳基炔,再将该N－芳亚甲基氨基芳基炔水解成氨基芳基炔。在一个实施方案中,本发明提供了一种制备氨基苯乙炔的方法,该方法包括:在碱和所述催化剂体系的存在下,将N－苯亚甲基氨基苯基卤与末端炔反应,生成一种新型N－苯亚甲基氨基苯乙炔,再将该N－苯亚甲基氨基苯乙炔水解成氨基苯乙炔。
