Abstract:

N-Heterocyclic carbene (NHC) plays an important role in catalytic processes, as the catalyst it has shown high activities in organic reactions. Synthesis of chiral triazole carbene, the structure and the application of NHCs in asymmetric catalytic benzoin reactions are described. The aims are to broad students' vision and make students feel the charm of organic chemistry through extension of undergraduate curriculum content. Meanwhile, their ability of finding, analyzing and solving problems on the basis of generalizing and thinking about the knowledge will be improved.

Key words: N-Heterocyclic carbene, Asymmetric reaction, Benzoin reaction, Aldehyde
