Scandium Chloride-Catalyzed Chemoselective Thioacetalization of Aldehydes

Abstract

A wide variety of acyclic and cyclic dithioacetals can be prepared chemoselectively from the corresponding aldehydes by employing a catalytic amount of scandium chloride in acetonitrile at room temperature.

scandium chloride - aldehydes - 1,3-dithiolanes - 1,3-dithianes - dithioacetals
