A dinitrosyl iron complex as a platform for metal-bound imidazole to N-heterocyclic carbene conversion

摘要

An N-alkyl imidazole bearing a neutral {FeCNO)_2}~(10) dinrtrosylinon complex (DNIC) when treated with sodium t-butoxide undergoes base-promoted conversion to the N-heterocyclic carbene (NHC)-DNIC, while maintaining the Fe(NO)_2 unit intact Subsequent allegation led to the isolation of the NHC-DNIC product; further nitrosyiation led to trinitrosyl (NHC)Fe(NO)_3~+. Both were isolated and structurally characterized.
