An approach towards the synthesis of 4‐phenyl‐5‐arylimino‐δ²‐1,2,3,4‐thiatriazolines

Abstract

4‐Phenyl‐5‐arylimino‐δ2‐1,2,3,4‐thiatriazolines are presumably formed by reacting 5‐arylaminothiatriazoles with benzyne at 50°, but decompose in situ to benzothiazole derivatives by way of the two pathways (a) and (b) shown in Scheme 4.
