Effect of TMEDA on Iron-Catalyzed Coupling Reactions of ArMgX with Alkyl Halides

Abstract
A new reaction mechanism for the iron-catalyzed cross-coupling reaction of ArMgX with alkyl halides using (TMEDA)FeAr2 and (TMEDA)Fe(Ar)Br is proposed on the basis of the isolation and reaction of these organoiron intermediates.
