Abstract

Ionic tagged 1, 4-Diazabicyclo [2.2. 2] octane (DABCO) grafted on magnetic nanoparticles (MNPs) was prepared and characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR), vibrating sample magnetometry (VSM) and thermal gravimetric analysis (TGA). The resulting magnetic solid supported DABCO catalyst with an ionic moiety was efficient for aza-Michael addition of ...
