| Abstract: | 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. |
