N-Alkylation of imides in the reaction of imides and alkylhalides, catalyzed by PT catalystsundersolvent-freeconditions, has been developed. The reaction occurs in the presence of K2CO3, and in many cases it takes place spontaneously. In the N-benzylation reaction, it has been recognized that TBAB (tetrabutylammonium bromide) and TBATFB (tetrabutylammonium tetrafluoroborate) show highest catalytic
已经开发了在无溶剂条件下由PT催化剂催化的酰亚胺和烷基卤化物的反应中酰亚胺的N-烷基化。该反应在K 2 CO 3的存在下发生,并且在许多情况下是自然发生的。在N-苄基化反应中,已经认识到TBAB(溴化四丁基铵)和TBAFB(四氟硼酸四丁基铵)显示出最高的催化作用。通过各种酰亚胺的N-苄基化和N-乙基化,已证实了无溶剂烷基化的多功能性和合成能力。所开发的方法使得容易获得N-(ω-溴烷基)酰亚胺。
