Abstract

Abstract The efficient synthesis of 2-arylbenzimidazole, 2-arylbenzothiazole and 2- arylbenzoxazole derivatives is described by condensation of aryl aldehydes and o- phenylenediamines, 2-aminothiophenol and 2-aminophenol in a single pot using a catalytic amount of vanadium (IV)–salen complex or vanadium–salen nanoparticles supported on silica (5.0 mol%) in excellent isolated yields. The immobilized catalyst was characterized ...
