The successful synthesis of mentioned derivatives was confirmed using Fourier-Transform InfraRed (FT-IR) as well as 1H/13C nuclear magnetic resonance (NMR) spectroscopies. According to the results, the employed nanocatalyst has some advantages such as high catalytic activity in short reaction time, good-to-excellent isolated yields in most cases, easy workup process, smooth processing feature of the reactions, facile recovery using an external magnetic field,  and re-usability for four times without significant loss in its activity.
