A wide range of aryl and heteroaryl bromides, which are usually sluggish in exchange reactions, are readily converted into the corresponding Grignard reagents by means of a Br/Mg exchange reaction triggered by iPrMgCl⋅LiCl (see scheme). These Grignard intermediates react with electrophiles in good yields.
