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.

By use of the condensation reaction of aryliminodimagnesium reagents (ArN(MgBr)2) with nitroarenes, six symmetrical and eight unsymmetrical azoxyarenes including four pairs of isomers were prepared in 40-80percent yields.The deoxygenation reaction of the azoxyarenes by treating with five molar equivalents of p-MeOC6H4N(MgBr)2 at 55 deg C in tetrahydrofuran was also studied, and the reactivity of deoxygenation was correlated to the shift of the electronic absorption maximum of azoxyarene.

When an equimolar solution of various azoxybenzenes and SbCl5 in carbon tetrachloride were mixed, a 1:1 complex immediately deposited as orange crystals in high yield.The thermal reaction of these complexes in inert solvents gives o-hydroxy-azobenzene selectively.On the contrary, other Lewis acids, such as TiCl4, AlCl3, FeCl3 and ZnBr2 failed to give an isolatable complex with azoxybenzene, and their direct thermal reaction with azoxybenzene resulted in deoxygenation to yield azobenzene as a main product.
