Intermolecular Carbophosphination of Alkynes with Phosphole Oxides via Ni−Al Bimetal‐Catalyzed C−P Bond Activation.

Intermolecular carbophosphination reaction of alkynes or alkenes with unreactive C−P bonds remains an elusive challenge. Herein, we used a Ni−Al bimetallic catalyst to realize an intermolecular carbophosphination reaction of alkynes with 5‐membered phosphole oxides, providing a series of 7‐membered phosphepines in up to 94 % yield.
