Nitrile Sulphides. Part 5. 1,3-Dipolar Cycloaddition of p-Methoxybenzonitrile Sulphide to Imines and Crystal Structure of One of the Resulting 4,5-Dihydro-1,2,4-thiadiazoles

p-Methoxybenzonitrile sulphide, generated by thermal fragmentation of the corresponding 1,3,4-oxathiazol-2-one, undergoes 1,3-dipolar cycloaddition to imines forming 4,5-dihydro-1,2,4-thiadiazoles.X-ray crystal structure analysis shows that the heterocyclic ring is non-planar with a fold of 30 deg about the S(1) - N(4) vector.

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.
