DABCO-based ionic liquid supported on magnetic core-shell nanoparticles, Fe3O4@SiO2/DABCO(OH), as a novel magnetic nanocomposite was prepared and characterized by Fourier Transform Infrared spectroscopy (FTIR), Scanning Electron Microscopy (SEM), X-ray powder Diffraction (XRD), Transmission Electron Microscopy (TEM) and Vibrating Sample Magnetometer (VSM) analysis. The hybrid nanocomposite was successfully used as an efficient heterogeneous basic catalyst for the facile synthesis of symmetrical dialkyl trithiocarbonates and cyclic trithiocarbonates from alkyl halides and epoxides respectively under mild reaction conditions. The results showed that aryl halides bearing electron-donating groups as well as electron-withdrawing groups converted to the corresponding symmetrical dialkyl trithiocarbonates in good to high isolated yields (80-95%). In addition, styrene oxide and phenyl glycidyl ether epoxide were converted to the corresponding cyclic trithiocarbonates in good yields in CS2 and the presence of nanocomposite without the formation of any by-product. Recycling experiments confirmed that Fe3O4@SiO2/DABCO(OH) was recyclable and could be used for several consecutive reaction runs.
