It has been established by chemical (2a) and CIDNP (3,4) techniques that some transition metal salts catalyze the reaction of Grignard reagents with alkyl halides by a mechanism involving free radicals. Such catalysis is probably responsible for the Wurtz coupling side reaction which lowers the yiel
