Some sulphur - containing double combination reagents

Abstract

Research and development of new reagents are very important for organic synthesis. In recent years, some new reagents with universal applicability have been reported, but new reagents of sulphur-containing are rarely reported. Wang’s group has developed several new sulphur-containing reagents which are called as Wang reagents: Sodium dithionite - tert-Butyl hydroperoxide (Na2S2O4-TBHP). The paper presents the reactions involved in the reagents obtaining and the associated mechanisms. Na2S2O4-TBHP is a new reagent for selective oxidation of aromatic alcohols to aldehydes. Wang reagents have universal applicability in organic synthesis.
