The precise control of the regioselectivity in the transition metal‐catalyzed migratory hydrofunctionalization of alkenes remains a big challenge. With a transient ketimine directing group, the nickel‐catalyzed migratory β‐selective hydroarylation and hydroalkenylation of alkenyl ketones has been realized with aryl boronic acids using alkyl halide as the mild hydride source for the first time. The...
Reported here is the discovery of a redox‐neutral NiII/NiII catalytic cycle which is capable of the linear‐selective hydroarylation of unactivated alkenes with arylboronic acids for the first time. This novel catalytic cycle, enabled by the use of an electron‐rich diimine ligand, features broad substrate scope, and excellent functional‐group and heterocycle compatibility under mild reaction conditions...
