A switchable formation of chloro‐ and enephosphorylamides from phosphorylamides and alkenes was disclosed herein. In the presence of Pd(OAc)2, a catalytic loading of CuBr or CuCl2 (20 mol‐%) led to the occurrence of dehydrogenative cross coupling reactions, while 1.0 equivalent of CuCl2 rendered the dehydrogenative amidochlorination reactions to take place in a stereoselective manner.
本文公开了由磷酰胺和烯烃可转换地形成氯-和烯基磷酰胺。在Pd(OAc)2存在下,CuBr或CuCl 2(20 mol%)的催化负载导致发生脱氢交叉偶联反应,而当量为1.0的CuCl 2使脱氢酰胺氯化反应发生在立体选择性的方式。
