A convenient protocol for highly selective delivery of azoxybenzenes from reduction of nitrobenzenes was developed by utilizing a coppercatalyst. A variety of functional groups and substitution were well tolerated.

Reaction of nitroso compounds with metal-carbene complexes and metal carbonyls has been investigated. These reactions lead to reduction of the nitroso compounds, primarily to the corresponding azo- and azoxy compounds. Metal-nitrene complexes have been proposed as intermediates in these reactions. These intermediates couple rapidly with the unreacted nitroso compound, or enter into nitrene-like reactions
