| Abstract: | A convenient one-pot cyclocondensation method for benzothiazole and benzimidazole syntheses is described. A set of benzothiazoles and benzimidazoles were readily prepared from aromatic ortho-diamines or ortho-aminothiophenol and aldehydes using chlorotrimethylsilane in dimethylformamide as promoter and water scavenger under ultrasonic irradiation in good yields (84–97%). |
