Heteroaromatic sulfonates and phosphates as electrophiles in iron-catalyzed cross-couplings.
Employment of heteroaromatic tosylates and phosphates as suitable electrophiles in iron-catalyzed cross-coupling reactions with alkyl Grignard reagents is reported. These reactions are performed at low temperature allowing good functional group tolerance and full conversion is achieved within minutes. In addition, an aryl-aryl cross-coupling utilizing a heteroaryl sulfamate electrophile is reported.
