2-Amino-5-methyl-1,3,4-thiadiazole and 2-amino-5-ethyl-1,3,4-thiadiazole
Acta Crystallographica Section C Crystal Structure Communications, 2001The structures of 2-amino-5-methyl-1,3,4-thiadiazole, C(3)H(5)N(3)S, and 2-amino-5-ethyl-1,3,4-thiadiazole, C(4)H(7)N(3)S, have been determined for comparison with unsubstituted 2-amino-1,3,4-thiadiazole. Despite their different space groups (P2(1)/n and Pbca, respectively), the packing modes of the methyl and ethyl derivatives are similar, with ...

Syntheses of arylsulfonyl‐1,3,4‐thiadiazoles
Journal of Heterocyclic Chemistry, 1996AbstractReaction of sodium arylsulfinate with 2‐aryl‐5‐chloro‐1,3,4‐thiadiazole gave 2‐aryl‐5‐arylsulfonyl‐1,3,4‐thiadiazole (3) in good yield. Starting from readily available 2‐amino‐5‐benzylmercapto‐1,3,4‐thiadiazole compound 7 was obtained in three steps in moderate yield.

S-ALKYL-2,5-DIMERCAPTO-1,3,4-THIADIAZOLES
Canadian Journal of Botany, 1958The synthesis and some fungitoxicity and phytotoxicity data are given for 2,5-dimercapto-1,3,4-thiadiazole and a series of its n-alkyl thioethers. These compounds exhibit a good measure of fungicidal activity, but would appear to be too toxic to the plants to be practical field fungicides.
