چکیده In the presence investigation, a cascade method for the synthesis of primary amides is discussed by the catalysis of Pd supported onto graphene oxide (Pd/GO) nanosheets. Also, the effect of different polyethyleneglycol-type (PEG-type) polyethers including PEG-300, P123 and F127 on the catalytic activity of Pd/rGO is studied in the the reaction of aldehyde and hydroxylamine hydrochloride to give benzamide. Addition of PEG-type polyethers played an important role in raising the catalytic power of Pd(nanoparticle)/GO by exfoliation of GO sheets. The present paper introduces Pd(nanoparticle)/GO as first Pd supported GO for the synthesis of primary amides through this method. This catalyst was highly active, efficient, tolerant, and environmentally benign in one-pot conditions with recyclability at least for 8 runs. Also, this study suggests the prevailing catalytic activity of Pd(nanoparticle)/GO rather to Pd(nanoparticle)/rGO in a comparitive experiment.
