Pd2(dba)3-Ph3P-catalyzed Kumada-Corriu coupling reactions of unactivated alkyl bromides or iodides with alkynyllithiums or the corresponding Grignard reagents furnish Csp-Csp3 bond formation. The superior performance of Ph3P ligand over the trialkylphosphine ligands indicates that this cross-coupling reaction may be a reductive-elimination-controlled process.
