A magnetite-reduced graphene oxide-supported CuO nanocomposite (rGO/Fe3O4-CuO) was preparedviaa facile chemical method and characterized by Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), UV-vis spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS), Brunauer-Emmett-Teller (BET) analysis, vibrating-sample magnetometry (VSM), and thermogravimetric (TG) analysis. The catalytic activity of the rGO/Fe3O4-CuO nanocomposite was probed in the direct oxidative amidation reaction of methylarenes with free amines. Various aromatic and aliphatic amides were prepared efficiently at room temperature from cheap raw chemicals usingtert-butyl hydroperoxide (TBHP) as a “green” oxidant and low-toxicity TBAI in water. This method combines the oxidation of methylarenes and amide bond formation into a single operation. Moreover, the synthesized nanocomposites can be separated from the reaction mixtures using an external magnet and reused in six consecutive runs without a noticeable decrease in the catalytic activity.

In this work, the mixture of formamide and 2,4,6-trichloro-1,3,5-triazine (cyanuric chloride or TCT) is introduced as a new amidating agent in Pd-catalyzed aminocarbonylation of aryl halides. In the presence of a catalytic amount of palladium and TCT/formamide reagent, a range of aryl halides (X = Cl, Br, I) were converted into amides efficiently in N,N-dimethylformamide at 120 °C. The 2,4,6-trichloro-1,3,5-triazine/formamide mixed reagent was found to be an efficient amidating agent in Pd-catalyzed aminocarbonylation of aryl halides. In the presence of this reagent and a catalytic amount of Pd, a range of amides were synthesized by using aryl halides.
