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.
