Nickel-Catalyzed Migratory Arylboration of Nonactivated Alkenes

An unprecedented nickel-catalyzed 1,n-arylboration (n >2) of terminal nonactivated alkenes has been developed. This reaction is the first example of a regioselective arylboration of terminal nonactivated alkenes and features high selectivity, wide functional-group tolerance, and operational simplicity. Remarkably, preliminary mechanistic studies indicated that an equilibrium of various nickel intermediates exists in this transformation, but bond formation is favored at the benzylic position.
