We have used tungestophosphoric acid to catalyze oxidative amidation reaction from benzyl alcohols and methylarens with hydrochloride salts of amines. To achieve this purpose, modified magnetic nanoparticles (γ-Fe2O3@SiO2@H3PW12O40) were applied as catalyst and TBHP as external oxidant. After optimizing, different derivates of benzamides were synthesized in good yields. Also, the result of two oxidative amidation reactions was compared.
