报道了无水AlCl3催化5种对位取代苯胺与丙烯腈发生Michael加成反应生成相应的N-氰乙基对位取代苯胺、N,N-二氰乙基对位取代苯胺,结果表明,AlCl3对该类反应具有很高的催化活性.在丙烯腈稍过量、较低温度、少量AlCl3催化剂的催化下,主要生成N-氰乙基对位取代苯胺,收率达88%～90%;在丙烯腈过量较多、75～85℃及较多AlCl3催化剂的催化下,主要生成N,N-二氰乙基对位取代苯胺,收率达88%～91%.当加入Lewis碱NaOAc作助催化剂时有利于提高N-氰乙基对位取代苯胺的选择性和收率;当加入Lewis酸ZnCl2作助催化剂时则有利于提高N,N-二氰乙基对位取代苯胺的选择性和收率.并对合成的5种N,N-二氰乙基对位取代苯胺用...

Michael addition reactions of acrylonitrile with p-substituted anilines have been carried out under various experimental conditions in the presence of AlCl 3, AlCl 3-NaOAc, or AlCl 3-ZnCl 2, resulting in N-β-cyanoethyl-p-substitutional anilines and N,N-bis(2-cyanoethyl)-p-substitutional anilines in high yields. And all of N,N-bis(2-cyanoethyl)-p-substituted anilines have been characterized by thermogravimetry, ultraviolet absorption spectrum, fourier transform infrared spectroscopy, elec...
