prepared from phosphorylamides and substituted alkenes. The dehydrogenative transformation took place in the presence of a combination of a palladium diacetate and nickel dichloride. The transition metal-catalyzed methodology enjoyed high efficiency and broad substrate scope. Moreover, a plausible mechanism was proposed for the oxidative C–N cross coupling protocol. Graphical Abstract
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.
