NUCLEOPHILIC SUBSTITUTION IN 1,2,3-THIADIAZOLES
Morzherin, Yu. Yu.,Tarasov, E. V.,Bakulev, V. A.
, p. 489 - 494 (1994)
By reactions of nucleophilic substitution of the halogen atom in 5-halo-1,2,3-thiadiazoles (IV), we have obtained 5-amino- (I, V), hydrazino- (VI, VII, IX, X), and mercapto- (VIII) 1,2,3-thiadiazoles.We show that upon reaction with amines, a mixture of 5-
