Abstract

Thiatriazoles. VII. 3‐Aroxy‐1,2,4‐dithiazole‐5‐imids of 5‐Amino‐1,2,3,4‐thiatriazole The unstable but isolable 3‐aroxy‐1,2,4‐dithiazole‐5‐imids ( 2a – d ) has been found on chlorothioformate acylation of 5‐amino‐1,2,3,4‐thiatriazole ( 1 ) in acetonitril. Further acylation and nucleophilic displacement reactions gave stable 3‐amino‐5‐acylimino‐1,2,4‐dithiazoles ( 6a – c , 7 ). The structure of the prepared compounds was inferred from their 1 H and 13 C‐n.m.r., mass spectra and corroborated by comparison with the data of similar derivates as well as by chemical means.
