Article abstract of DOI:10.1016/0040-4020(80)87026-8

3-Vinyl-1,2,5-thiadiazole is prepared by different methods: by one-pot reaction from 1,2,5-thiadiazole, by cyclization of 3,4-diamino-1-butene, and by the Wittig procedure either from 1,2,5-thiadiazolylmethylenetriphenylphosphorane or from 3-formyl-1,2,5-thiadiazole.Some physical and chemical properties are described.
