Chemoselective Synthesis of Pentaerythritol Diacetals Catalyzed by CuO-CeO2 Nanocomposite under Solvent-free Conditions

Document Type: Research Paper



CuO-CeO2 nanocomposite is reported as a green recyclable catalyst for the chemoselective synthesis of pentaerythritol diacetals from aromatic aldehydes under solvent-free conditions. The catalyst was synthesized by co-precipitation method and characterized by XRD, BET specific surface area, FESEM and EDS analysis. This procedure provides some advantages such as simple work-up, clean procedure, short reaction times and high yields of the products.
