Abstract

An efficient and selective oxidation of benzoins into corresponding benzils using chromium trioxide under viscous conditions at room temperature is described. The present oxidations are completed within 2 h with the yield of 86–96%. It can overcome the problems of the common solvent-free reactions, in which it is difficult for the solid molecular collision to react.

Notes

a All the products are known compounds and were identified by comparison of their melting points with the literature values as well as by 1H NMR and IR.

b Yields of isolated pure products.
