A Green Recyclable Poly(4-Vinylpyridine)-Supported Copper Iodide Nanoparticle Catalyst for the Chemoselective Synthesis of Pentaerythritol Diacetals from Aromatic Aldehydes

Abstract

Poly(4-vinylpyridine)-supported copper(I) iodide nanoparticles have been used as an efficient, green recyclable catalyst for the chemoselective synthesis of pentaerythritol diacetals from aromatic aldehydes and pentaerythritol under solvent-free conditions. This catalyst was reused six times without any loss of its activity.We thank the Behbahan Khatam Alanbia University of Technology for partial support of this work.

CuO-CeO2 Nanocomposite: An Efficient Recyclable Catalyst for the Synthesis of Aryl-14H-dibenzo[a-j]xanthenes

“…Therefore, various catalysts have been developed for the improvement of this reaction [16][17][18][19][20][21][22][23][24][25]. In the continuation of our research program to develop the efficient, and green catalysts in organic synthesis [26][27][28][29], herein, we wish to report a green, efficient and recyclable catalyst for the synthesis of Aryl-14H-dibenzo[a-j]xanthenes under solvent-free conditions (Scheme 1).…”
