چکیده مقاله:
A novel magnetically immobilized polyethyleneimine (PEI) fabricated by covalently anchoring on MCM-۴۱(MCM-۴۱@PEI) was prepared. The synthesized catalyst was characterized by Fourier transform infrared (FT-IR),thermogravimetric analysis (TGA), X-ray powder diffraction (XRD), scanning electron microscopy (SEM) andtransmission electron microscopy (TEM). The immobilized PEI was shown to be an efficient heterogeneous catalystfor the synthesis of spiro-oxindole and benzopyranes derivatives via multi-component reaction (MCR), in ethyleneglycol as a green solvent. No leaching problem was observed after several runs, while the catalyst can be recoveredand reused without loss of reactivity under the described reaction conditions.
