Nitrile sulphides, generated by thermal decarboxylation of 1,3,4-oxathiazol-2-ones, undergo 1,3-dipolar cycloaddition to trichloroacetonitrile yielding 5-trichloromethyl-1,2,4-thiadiazoles (45-66%). The reaction of the cycloadducts with secondary ami

The carbon–nitrogen triple bond of aryl thiocyanates acts as a dipolarophile in 1,3-dipolar cycloadditions. Reaction with nitrile oxides, nitrile sulphides, and benzonitrile N-phenylimide yields, respectively, 5-arylthio-1,2,4-oxadiazoles, -thiadia

3-Aryl-5-methylthio-1,4,2-dithiazolium salts, prepared by treatment of the corresponding 1,4,2-dithiazole-5-thiones with dimethyl sulphate, react with aniline and with active methylene compounds to form, respectively, 5-phenylimino- and 5-alkylidene-

1,4,2-Dithiazole-5-thiones can act either as the 2-atom or the 3-atom component in 2 + 3-cycloadditions. Benzonitrile N-phenylimine, generated in situ by dehydrochlorination of N-phenylbenzohydrazonoyl chloride, reacts at the exocyclic CS double bond
