Selective Thioacetalization of Aldehydes Catalyzed by Aqueous Zinc Tetrafluoroborate

Abstract

A wide range of cyclic dithioacetals are prepared from the corresponding aldehydes in the presence of aqueous solution of zinc tetrafluoroborate.

Keywords:

• Dithioacetals
• Aqueous zinc tetrafluoroborate
• 1,2‐Ethanedithiol
• 1,3‐Propanedithiol
