MICROWAVE-INDUCED SOLVENT-FREE SYNTHESIS OF 2-ARYLBENZOTHIAZOLES USING p-TsOH

ABSTRACT

A simple and efficient procedure has been developed for the synthesis of 2-arylbenzothiazoles by a one-pot reaction of o-aminothiophenol with β-chlorocinnamaldehydes using p-TsOH under microwave irradiation.

Keywords:

• 2-Arylbenzothiazoles
