标题:Oxidative Coupling of Aromatic Amines and Nitrosoarenes: Iodine-Mediated Formation of Unsymmetrical Aromatic Azoxy Compounds

AbstactI2/DABCO (iodine/1,4-diazabicyclo [2.2.2]octane)-mediated oxidative coupling of nitrosobenzenes with aromatic amines was revealed to lead to the production of unsymmetrical aromatic azoxy compounds, instead of azo compounds reported previously in Mills reaction. Our study illustrates that various aromatic amines can be efficiently coupled with nitrosobenzenes to produce unsymmetrical azoxy product, in which more than thirty unsymmetrical azoxybenzenes have been successfully prepared. The applicability to a broad range of substrates, scalability to large scales and mild reaction conditions make this new synthetic protocol very practical, providing a convenient and direct access to unsymmetrical azoxybenzenes
