THE THERMAL FRAGMENTATION OF 1,3,4-DITHIAZOL-2-ONES

Thermal expulsion of carbon oxysulphide from 1,3,4-dithiazol-2-ones in the presence of DMAD affords nitrile sulphide-derived dimethyl isothiazole-4,5-dicarboxylates.

Cycloaddition Reaction of 1,4,2-Dithiazole-5-thiones

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 C=S double bond forming the thiadiazolethione (17) and the spiro compound (18) by collapse of the initial cycloadduct (19) and further 1,3-dipolar cycloaddition.The corresponding reaction with ethyl azidoformate yields a 5-ethoxycarbonylimino-1,4,2-dithiazole.On treatment-with dimethyl acetylenedicarboxylate and ethylcyanoformate the dithiazolethione itself acts as a 1,3-dipole forming 1,3-dithiole and 1,4,2-dithiazolethiones with expulsion of a nitrile fragment.
