Abstract

CdO nanoparticles efficiently catalyzes the condensation of aromatic aldehydes with 2-aminophenol at room temperature to afford 2-aryl benzoxazole derivatives by grinding method. The reactions proceed under heterogeneous and mild conditions to provide 2-aryl benzoxazoles in excellent yields (87-97 %) with high purity under solvent free condition. The reaction requires short time (5-23 minutes) under moderate conditions. The purification of products by non-chromatographic methods is additional feature of this method. A series of 2-aryl bezoxazole have been successfully synthesized by this method. Ease of recycled catalyst, cleaner process, solvent free and lower catalytic loading are the most advantages of the proposed method.
