Abstract
A convenient and efficient modular approach to the synthesis of polydentate NHC ligand precursors (benzimidazolium salts) containing axial chiral 1,1′-binaphthyl from 1,2-diaminobenzene and BINOL has been developed. The benzimidazolium salts could be regarded as the potential bidentate, tridentate, and tetradentate NHC ligand precursors.
