摘要
The present invention comprises a process for catalytic oxidative ammination of aromatic hydrocarbons which comprising contacting aromatic feedstock with oxidant, such as molecular oxygen, under suitable reaction conditions, in the presence of a catalyst comprising three essential components: a support; transition metal; and a mono- or binucleating ligand. In one embodiment of the invention the ligand comprises at least one nitro or nitroso group. In another embodiment, the ligand comprises a multidentate, chelating binuclear compound. The process is particularly suited, for example, to the one-step conversion of benzene to aniline.
