A three-component reaction of alkynes, arylzinc chlorides, and iodomethanes was found to proceed in the presence of a rhodium catalyst to give high yields of trisubstituted/tetrasubstituted alkenes. The usual arylzinc chlorides only gave trisubstitutedalkenes, generated through a migratory carbozincation–cross-coupling sequence, where 1,4-Rh migration from an alkenyl carbon to an aryl carbon occurred
