By means of regioselective S-alkylation of 1H-1,2,4-triazole-3-thiol (1), a series of S-substituted derivatives 2a-j were synthesized. In certain conditions, the reaction of 2 with arylsulfochlorides, arylisocyanates, and quaternary ammonium salts of azines corresponding compounds were obtained 1-arylsulfonyl- (3a-d), 1-arylcarbonamido- (4a,b), and 1-azinyl-1,2,4- (6a-p) triazoles.
