A copper-catalyzed oxidative dehydrogenative coupling of nitrosobenzenes with anilines for the synthesis of unsymmetrical azoxybenzenes was developed. This approach uses O2 as the oxidant. The reaction products are diverse unsymmetrical azoxybe

Perfluoroalkyl azo dyes were prepared by the reaction of azo compounds with bis(perfluoroalkanoyl) peroxides.The absorption spectra and melting points of the perfluoroalkyl azo dyes were also examined.

The reaction of 2-lithio-1,3-dithianes with nitroarenes gives 2-(or 4-)cyclohexa-3,5(or 2,5-)-diene-1-nitronate compounds (conjugate-addition products), free nitroarene radical anions (redox products), 1,3-dithianes and 2,2'-bis-(1,3-dithianes).The conjugate-addition and redox products were converted in the respective nitroaromatic compounds by oxidation in situ with O2 or DDQ.The ratio between addition and redox products increases with decrease of temperature. 2-H-2-Lithio-1,3-dithiane can give both 1,4- and 1,6-addition products, while 2-methyl- and 2-phenyl derivatives give only 1,6-addition products.A mechanism involving an s.e.t. from lithium dithianes to nitroarenes followed by various decay routes is suggested for the two radical species.
