چکیده مقاله :
In the present study, application of porous acidic catalyst functionalized with an imidazoleionic liquid ([SBA-Im]HSO4) as a phase transfer catalyst for the facile preparation of benzylthiocyanates and azides in water has been described. The catalyst has been characterized byFourier transform infrared spectroscopy (FT-IR), scanning electron microscope (SEM), transmissionelectron microscopy (TEM), thermogravimetric analysis (TGA) and derivative thermogravimetricanalysis (DTG). The polymeric phase transfer catalyst, easily recovered by simplefiltration, shows no appreciable loss of activity when recycled several times.
