Abstract:

Azobenzene and azoxybenzene compounds have exhibited broad application prospects in the fields of pigments, optical materials, fluorescent probes, and optoelectronic devices. Now many catalysts and oxidants have been developed for the oxidation coupling reaction of aniline to produce azobenzene and azoxybenzene compounds, and among them, developing the green, eco-friendly oxidation systems is still a hot but challenging issue in the current researches. Based on the above, this review summarizes the recent progress in catalyzing the selective oxidation of aniline to generate azobenzene and azoxybenzene compounds with the use of hydrogen peroxide and oxygen as oxidants, and meanwhile, discusses the possible mechanisms of aniline oxidation, mainly including nitrosobenzene intermediate mechanism and radical coupling mechanism. Finally, the potential problems and challenges in the synthesis of catalysts and the catalytic mechanisms have been summarized, and further researches have been prospected. This review will provide an important reference for the development of related fields.

Key words: Aniline, Selective oxidative coupling, Hydrogen peroxide, Oxygen, Azo compound
