Synthesis and Characterization of Some Derivatives of 1,3-Diisopropyl-4,5-dimethylimidazol-2-ylidene

Abstract

N-Heterocyclic carbenes are widely used in organic reactions and coordination chemistry. In the present study, 2,3-dihydro-1,3-diisopropyl-4,5-dimethylimidazol-2-ylidene (1) is reacted with diphenyl disulfide, methyl phenyl disulfide, and bis(methylsulfonyl)methane to yield target compounds 5, 6, and 7 respectively. Structures of these compounds are well established using nuclear magnetic resonance, mass spectrometry and elemental analysis. Possible reaction mechanisms are proposed.
