摘要:Chiral 1, 3-diarylimidazole salt carbene precursors, their methods of preparation, particularly transition metal complexes and their use in chemical synthesis are provided. In particular, an air and moisture stable chiral 1, 3-diarylimidazole carbene precursor Cu (I) complex has been prepared and applied to highly regio- and enantioselective Markovnikov hydroboration of unactivated terminal alkenes to form chiral boronic esters. Moreover, these new chiral NHCs can be potentially applied in various metal-catalyzed asymmetric transformations.
