They are capable of reacting with different nucleophiles and their potential in the ring-opening of epoxides adds to their importance as pioneers in the synthesis of organic compounds. In the present research, a green and easy method for the synthesis of zinc oxide nanoparticles as a catalyst has been expressed. Synthesized zinc oxide nanoparticles were characterized by UV-Vis spectroscopy, Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), and scanning electron microscopy (SEM). The UV-Vis spectrum of the nanoparticles showed an absorption peak at 327 nm corresponding to the ZnO nanoparticles. X-ray diffraction analysis also showed a high degree of crystallinity of the synthesized nanoparticles with the hexagonal structure. Zinc oxide nanoparticles were studied as an effective catalyst for epoxide ring-opening. The reactions were done by aliphatic and aromatic amines and alcohols as a nucleophile at room temperature and under microwave conditions. The results of the reactions show that the presence of zinc oxide nanoparticles catalyzes the ring-opening of the epoxides well. The ZnO nanocatalyst leads to the synthesis of products with high efficiency and good regioselectivity in a short period of time. %U https://www.pcbiochemres.com/article_141625_38cb12b3c49e83710fcd587442cbd5d6.pdf
