Magnetic γ-Fe2O3@Cu-LDH intercalated with Palladium Cysteine: An efficient dual nano catalyst in tandem CN coupling and cyclization progress of synthesis quinolines

摘要: Abstract The novel magnetic γ-Fe2O3@Cu-LDH@Cysteine-Pd dual nanocatalyst system was designed through a combination of MNPs and LDH to improve separation promote the catalytic features. In this regard, facile surface modulation by substitution copper (II) metal cations with obtained. Also, interface defect structure modified via immobilization Pd complex as an active catalyst. synthesized biocompatible catalyst employed in economical method using A3-coupling followed C N coupling intramolecular cyclization for synthesis quinolines prove efficiency. Quinoline derivatives were achieved tandem one-pot from 2-bromo benzaldehyde low cost available starting material presence excellent yield. recovered could be efficient up fourth cycle. confirmed several useful analyses such FT-IR, TGA, VSM, SEM, TEM, XRD, ICP.
