A Convenient Method for Dethioacetalization of 1,3-Dithiolane and 1,3-Dithianes using Benzyltriphenylphosphonium Peroxymonosulfate in Aprotic Solvent

Abstract

Benzyltriphenylphosphonium peroxymonosulfate in the presence of bismuth chloride was found to be an efficient and mild reagent for the dethioacetalization of 1,3-dithiolanes and 1,3-dithianes to the corresponding carbonyl compounds under aprotic conditions.
