Abstract :
In this study, nanocatalysts of GO/ZnO/Mn/Co for the reaction of xanthene and amido alkyl naphthol were studied. First, the optimal conditions for these two reactions were obtained and then the effect of zinc oxide nanoparticles on this reaction was studied. To do this, study the graphene oxide catalyst with the presence and absence of ZnO and then different conditions such as the amount of catalysis, the reaction temperature, the reaction time, and finally the appropriate solvent to perform both reactions optimally. Finally, the conditions of these reactions for the synthesized of derivatives under thermal and ultrasonic conditions are studied and the results show that this catalyst has a good ability to perform these two reactions because with a small amount of catalyst excellent yield is obtained with high efficiency and also recyclability several times for xanthene and amido alkyl naphthol derivatives. The products were characterized by FT-IR, NMR spectra, and melting point.
