Trichloroisocyanuric Acid (TCCA) as a Mild and Efficient Catalyst for the Synthesis of 2-Arylbenzothiazoles

The condensation reaction of 2-aminothiophenol with aldehydes catalyzed by 1 mol % trichloroisocyanuric acid (TCCA) was investigated. As a result, a set of diverse 2-arylbenzothiazoles were obtained in good to excellent yields at room temperature.
