Abstract

Chiral vanadium complex prepared in situ from VO(acac)2 and Schiff base 9 was found to be an efficient catalyst for oxidation of various methyl aryl sulfides with hydrogen peroxide as terminal oxidant. For example, oxidation of methyl 2-naphthyl sulfide using a VO(acac)2, 9, and hydrogen peroxide system proceeded with high enantioselectivity of 93% ee as well as acceptable chemical yield.
