Solid supported catalysts such as amines are in high demand for the chem. fixation of CO2 into commodity chems. Here, we demonstrate an accelerated platform for 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU)-ionic liquid (IL) catalyzed CO2 fixation via the grafting of DBU-ILs over magnetically separable Fe3O4 nanoparticles (MNPs). The DBU-ILs were covalently immobilized over Fe3O4 MNPs utilizing the thio-ene reaction of allyl-DBU with -SH modified Fe3O4 MNPs. The DBU-IL-grafted Fe3O4 (Fe3O4@DBU-ILs) materials were characterized by Fourier-transform IR spectroscopy, field-emission SEM, transmission electron microscopy, XPS, thermogravimetric anal. and vibrating-sample magnetometry. TEM revealed that the MNPs have a spherical structure with a particle size of 12-20 nm. VSM showed the gradual decrease in magnetization after stepwise grafting from Fe3O4 to Fe3O4@DBU-ILs. The efficacy of the two different Fe3O4@DBU-ILs, Fe3O4@[HDBU+][TFE-] and Fe3O4@[HDBU+][AcO-] prepared by neutralization of Fe3O4@DBU with 2,2,2-trifluoroethanol (TFE) and acetic acid (AcOH), was investigated by simultaneous fixation of CO2 into the important heterocyclic compounds quinazoline-2,4(1H,3H)-dione and benzimidazolone. This approach shows excellent recyclability with a nominal decrease (2-3%) in product yields after each cycle. In particular, the energy-dispersive X-ray spectroscopy mapping of Fe3O4@[HDBU+][TFE-] used for five cycles demonstrated significant leaching of TFE. Interestingly, after retreatment with TFE, Fe3O4@[HDBU+][TFE-] showed a similar yield to that of a fresh catalyst.
