A very rapid, convenient, and general method for the synthesis of alpha-oxo thiocyanates has been described by using clay supported ammonium thiocyanate. The procedure avoids the use of additional catalyst, solvent, aqueous work-up and the yields are high. Moreover, the method is applicable for a variety of aryl, heteroaryl, alkyl alpha-halo carbonyls, beta-keto tosylates, alpha-halo beta-dicarbonyl, alpha-tosyl, beta-dicarbonyl, alkyl halide, and alkyl tosylates.
