Abstract

Catalytic alkene hydroalkylation has provided to be an efficient method for synthesizing C(sp3) centers, from readily available and inexpensive alkene starting materials through alkene hydrometallation followed by cross-coupling. One of the major tasks in this field is to develop diverse ligands to achieve regioselective control. Herein, we report the investigation of nickel–triphenylphosphine-catalyzed remote hydroalkylation of alkenyl amides to access α-branched amines. Various alkenes and alkyl iodides are suitable substrates to deliver the desired products with excellent regioselectivities (>20:1 regioisomeric ratio). Density functional theory calculations reveal the reaction mechanism.
