• <i>N</i>-Alkylation of imides using phase transfer catalysts under solvent-free conditions
  作者：Jolanta Jaśkowska、Piotr Kowalski

  DOI：10.1002/jhet.5570450519

  日期：2008.9

  N-Alkylation of imides in the reaction of imides and alkylhalides, catalyzed by PT catalysts under solvent-free conditions, 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。
