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. %U https://www.orgchemres.org/article_15519_d81b7d3a9d31e9bb581795c2e5804808.pdf
