Heteropoly Acids as Heterogeneous and Reusable Catalyst for α-Thiocyanation of Ketones

Abstract

Simple, efficient, and mild method for α-thiocyanation of ketones in presence of heteropolyacid has been developed. This methodology offered α-oxothiocyanates in good to excellent yields at room temperature in a highly selective manner. The catalyst could be efficiently recovered from the reaction and reused.

Keywords:

• Ketones
