A series of chiral bidentate ligands were designed and synthesized, and their complexes, which derived from coordinating with Ti(OPr-i)4, were employed in the catalytic asymmetric oxidation of sulfide. Both the influence of the structure of the chiral ligands to the reactivity and enantioselectivity and the relationship of the configurations between the chiral ligands andthe products were investigated.

Key words: chiral ligand, catalysis, sulfide, asymmetric oxidation
