A silver(I) oxide-mediated synthesis of unsymmetrical aromatic azoxy compounds has been successfully achieved, wherein oxidative coupling reactions between aromatic amines and nitrosoarenes take place in ethanol under air. This reaction has very high economic value because silver(I) oxide is the only oxidant required and no other additive is needed. The resulted silver particles can be easily recovered, while the only other byproduct is water. This new procedure is compatible with various functional groups and proceeds under mild reaction conditions.
