Aromatic Poly‐1,3,4‐Thiadiazole Fibers

Journal of Polymer Science Part C: Polymer Symposia, 1967
AbstractIt has been shown that aromatic poly‐1,3,4‐thiadiazole fibers can be prepared in a manner analogous to that of the aromatic poly‐1,3,4‐oxadiazole via the thermal cyclode‐hydration of an aromatic polyoxathiahydrazide fiber. These fibers exhibited the same high level of thermal and hydrolytic stability observed for the aromatic poly‐1,3,4 ...

2-Amino-5-methyl-1,3,4-thiadiazole and 2-amino-5-ethyl-1,3,4-thiadiazole

Acta Crystallographica Section C Crystal Structure Communications, 2001
The 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, 1996
AbstractReaction 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, 1958
The 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.
