A 1,2,3-thiadiazole–1,2,3-thiadiazole rearrangement
J. Chem. Soc., Chem. Commun., 1983During its preparation, 4-ethoxycarbonyl-5-diazomethyl-1,2,3-thiadiazole (4), undergoes a ring transformation into the isomeric structure (5), but when the ester function in (4) is replaced by a phenyl group, no isomerization is observed.

Publisher Summary This chapter presents the review of organic and physical chemistry of monocyclic 1, 2, 5-thiadiazoles up to the early part of 1967. Reference is made to the 2, 1, 3-benzothiadiazoles and related compounds only as they contribute to the chemistry of the basic ring system. The 1, 2, 5-thiadiazole nucleus is numbered as in 4.

Abstract The microwave spectra of 1, 3, 4-thiadiazole (I) and [ 34 S] 1, 3, 4-thiadiazole (II) have been recorded in the 15,000–30,000 Mc/sec region. Twelve and ten transitions, respectively, were assigned. The rotational constants of (I) are, A = 8907.51 ± 0.10, B = 5569.27 ± 0.02, and C = 3424.80 ± 0.03 Mc/sec. For (II), A = 8908.15 ± 0.20,

Heterocycles containing nitrogen, oxygen and sulfur have been under investigation for a long time because of their important medicinal properties. The literature survey has described that thiadiazole moieties serve as analgesic, anti-inflammatory, anti-microbial activities, antihypertensive,anticancer, antituberculosis and vasodilator and this ...
