Super Paramagnetic, MCM-41-Supported, Recyclable Copper-Complexed Dendrimer: A Novel Nanostructured Catalyst for Propargylamine Synthesis Under Solvent-Free Conditions

A super paramagnetic MCM-41 with dendrites copper complex is prepared and characterized using FT-IR, BET, AAS, TEM, CV, TGA, X-ray and VSM. The catalyst was used in C-H activation reaction for the synthesis of propargylamines by the reaction of aldehydes, amines and phenylacetylene under solvent-free conditions. Finally the catalyst was separated using an external magnet and reused many times.
