Direct and to the point: The simple precatalyst system FeCl3/TMEDA has been effectively applied to cross-coupling reactions of various arylmagnesium bromides and alkenyl bromides. With activated aryl bromides and in the absence of polar functional groups, the method can be modified to allow for domino iron-catalyzed magnesiation–cross-coupling reactions.
