Abstract
2-Substituted benzothiazoles have been efficiently synthesized in good yields by the condensation reaction of o-aminothiophenol with aldehydes in the presence of a catalytic amount of perchloric acid–doped polyaniline (HClO4/PANI). The low cost, simple recovery, and efficient reusability are remarkable characteristics of this catalyst.
We are thankful to the Yazd University Research Council for partial support of this work.
