(NHC)2FeCl2 complexes undergo methoxide transfer in preference to aryl transfer from [(Aryl)B(OR)3]鈭?/sup>, while addition of ArylBY2 (Y = Cl, OR) to (NHC)Fe鈥搈ethoxide compounds leads only to formation of (NHC)BY2Aryl. The addition of PhBCl2 to (NHC)2FeX2 compounds is introduced as a method for probing NHC dissociation from iron. Two expanded ring NHCs also undergo dissociation from iron in the respective (NHC)2FeCl2 complexes.
