The use of the Xantphos ligand in a mild palladium-catalyzed Kumada-Corriu reaction of secondary benzylic bromides with aryl and alkenyl Grignard reagents minimizes the undesired β-elimination pathway. The corresponding cross-coupling products can be isolated in good yields with inversion of the configuration.
