Niobium(V) chloride catalyzed oxidation of dithioacetals with 30% hydrogen peroxide: a concise preparation of bissulfonylmethylene compounds

Chem Pharm Bull (Tokyo). 2013;61(4):460-3. doi: 10.1248/cpb.c12-00826.

Abstract

The oxidation of dithioacetals with 16 eq of 30% hydrogen peroxide in the presence of 10 mol% niobium(V) chloride at room temperature provides bissulfonylmethylenes in high yields.
