Synthesis and characterization of copper (II)-poly(acrylic acid)/M-MCM-41 nanocomposite as a novel mesoporous solid acid catalyst for the one-pot synthesis of polyhydroquinoline derivatives

A novel, green and recoverable nanocomposite was designed, synthesized and fully characterized. The resulting nanocomposite have successfully used as a catalyst for the condensation of various aromatic aldehydes, dimedone, ß-ketoester and ammonium acetate under mild and solvent free conditions to yield polyhydroquinoline derivatives in good to excellent yields.
