Abstract
Copper supported on periodic mesoporous organosilica (PMO) with alkylimidazolium frameworks is a highly efficient and recoverable catalyst for the preparation of propargylamines through the three-component coupling reaction of aldehydes, alkynes, and amines. The new catalyst is characterized using N2 adsorption/desorption analysis, transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS), thermogravimetric analysis (TGA), diffuse reflectance infrared Fourier transform spectroscopy (DRIFT-IR), and elemental analysis. The catalyst is easily recovered by a simple filtration process and subsequently reused in the seven reaction cycles without any loss of catalytic activity.
