Efficient 2,4,6‐trichloro‐1,3,5‐triazine‐catalyzed synthesis of 2‐arylbenzothiazoles and bisbenzothiazoles by condensation of 2‐aminithiophenol with aldehydes under mild conditions

Abstract 2,4,6‐Trichloro‐1,3,5‐triazine efficiently catalyzed the condensation reactions between 2‐aminothiophenol and aromatic aldehydes to afford 2‐arylbenzothiazolles in good‐to‐excellent yields. Simple and mild reaction conditions, the use of a cheap catalyst and easy work up, and isolation are notable features of this method. J. Heterocyclic Chem., (2011).
