A very rapid, convenient, and general method for the synthesis of α-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 α-halo carbonyls, β-keto tosylates, α-halo β-dicarbonyl, α-tosyl, β-dicarbonyl, alkyl halide, and alkyl tosylates.

An efficient and convenient method for-thiocyanation of ketones and-dicarbonyl compounds has been developed using a reagent combination of bromodimethylsulfonium bromide (BDMS) and ammonium thiocyanate in acetonitrile. The developed method is mild and gave good yield of the products at room temperature.

Novel N-thiazolo-1,3-oxathiol-2-imines are synthesized by reaction of a-haloketones with potassium thiocyanate-silica gel. It is thought that the reaction occurs through conversion of the α-haloketone into the corresponding thiocyanate which then undergoes acid-catalyzed intramolecular cyclization to yield a cationic intermediate. Subsequent reaction of this intermediate with another molecule of the α-thiocyanatoketone and a second cyclization then gives the N-thiazolo-1,3-oxathiol-2-imine.
