In this paper, we have studied the asymmetric Baeyer-Villiger reaction of 2-phenylcyclohexanone catalyzed by Cu(Ⅱ) complexes which derived from a series of chiral Salen and oxazoline ligands, as well as designed and synthesized the new chiral ligands Ⅲ, Ⅳ, Ⅴ. And the configuration of complex Ⅴ-Cu(Ⅱ) was determined by X-ray analysis. We also investigated the influence of co-oxidant, solvent, etc. on the reactivity and selectivity.
