Syntheses and properties of 2,5-diamino-1,3,4-thiadiazole, 3,5-diamino-1,2,4-thiadiazole and 3-N-alkyl-5-amino-2-imino-1,3,4-thiadiazolines -building blocks for macroheterocyclic compounds are discussed in this review. The convenient methods of their synthesis were elaborated and peculiarities of their geometrical structure were discussed. The mechanism of 3,5-diamino-1,2,4-thiadiazole formation from 2-imino-4-thiobiuret was simulated by quantum chemistry methods at the level of Density Functional Theory (DFT).
