A mild palladium-catalyzed Kumada−Corriu reaction of secondary benzylic bromides with aryl and alkenyl Grignardreagents has been developed. In the presence of the Xantphos ligand, the undesired β-elimination pathway is minimized, affording the corresponding cross-coupling products in acceptable to good yields. The reaction proceeds with inversion of the configuration.

The inexpensive borane dimethylsulfide (BMS) complex was found to be an efficient hydride source for nickel‐hydride catalyzed migratory hydrofunctionalization. Using BMS, migratory hydroarylation and migratory hydroalkenylation were achieved with broad substrate scope under mild conditions.
