A simple and efficient procedure was developed for the preparation of a variety of aryl, hetero aryl and alkyl N-sulfinylimines (2b-2u) with excellent yields (85–94%) using tungstophosphoric acid as catalyst. Also, this new synthetic protocol features high conversion, shorter reaction time, a straight forward and simple work up procedure. Catalyst was recycled for 10 times without much loss in activity
开发了一种简单有效的方法,使用钨磷酸作为催化剂,可制备多种芳基,杂芳基和烷基N-亚磺酰亚胺(2b-2u),并具有优异的收率(85-94%)。而且,这种新的合成方案具有高转化率,更短的反应时间,简单明了的后处理程序。催化剂循环使用了10次,活性没有太大损失,并且以克为单位进行了放大,收率很高。因此,它非常适用于工业规模放大过程。
