Abstract
Abstract A series of 1-aryl-1H,3H-thiazolo[3,4-a]benzimidazole derivatives have been synthesized via the three-component reaction of o-phenylenediamine, aromatic aldehydes, and 2-mercaptoacetic acid, catalyzed by magnetite-linked sulfonic acid. This method has the advantages of high yield, extensive adaptability, easy operation, and environmental friendliness. Supporting this acid catalyst on magnetite particles offers a simple and nonenergy-intensive method for recovery and reuse of the catalyst by applying an external magnet.
