Synthesis of 2-Aryl-4,6-dinitrobenzo[d]isothiazolium from 2,4,6-Trinitrotoluene.

-A facile method for the synthesis of previously unknown benzothiazolium salts (VI) based on the replacement of an ortho-NO2 group in trinitrobenzylideneanilines (I) with Bn-SH followed by intramolecular cyclization of the substitution products is developed. -(SAPOZHNIKOV, O.
