Quantum-chemical calculations and X-ray diffraction data for a series of N-substituted p-quinon-imines showed that the PM3 method is the most suitable for determination of geometric parameters of these compounds. Moreover, it can be used to predict the site of addition of chlorine and bromine in the hydrohalogenation reaction.

The study of chlorination of N-(N-arylsulfonylarylimidoyl)-1, 4-benzoquinone imines and of N-(N-arylsulfonylarylimidoyl)-1,4-aminophenols revealed that the dominant stage in the process was the formation of cyclohexene structures, 4-(N-arylsulfonylarylimidoyl)imino-2,5,6-trichloro-2-cyclohexene-1-ones, resulting from addition of a Cl2 molecule across the C=C bond of the quinoid ring. These substances suffer a prototropic rearrangements yielding N-(N-arylsulfonylarylimidoyl)-2,3,6-trichloro-4-aminophenols. The latter are the most common reaction products. The products of deeper chlorination were also obtained.
