Abstract

A new method has been developed for converting nitriles into primary thioamides. Treatment of various nitriles (Table [1] , entries 1-12) with gaseous hydrogen sulfide in a mixture of methanol-water or ethanol-water and in the presence of anion-exchange resin (Dowex 1X8, SH- form) at room temperature and ambient pressure gave the corresponding thioamides in 25-96% yield.
