Abstract

Alkenes and alkynes react readily with trithiazyl trichloride 1 to give 1, 2, 5-thiadiazoles 2 in one step. Thus 3-amino-1, 2, 5-thiadiazole 5 is now readily available from N- vinylphthalimide and 1 in two steps. Cyclic alkenes react similarly to give fused thiadiazoles (7, 12) and phenanthrene gives the phenanthrothiadiazole 16. Tetra-substituted alkenes such as 13 appear to give the analogous 3, 4-dihydrothiadiazoles (eg 14) which ...
