Reactions of [FeL2(CH3CN)2]2+(L = N-pyrimid-2-ylimidazolylidene) with various N-,P-,O-,and S-donors were investigated.By replacing the labile acetonitrile,various iron-NHC complexes containing additional N-,P-,O-,and S-ligands were prepared.All the iron-NHC complexes were fully characterized by NMR spectroscopy and X-ray crystallography.[FeL2(CH3CN)2]2+ could efficiently catalyze the coupling reactions of various Grignard reagents with heteroaryl bromides or chlorides.
