Quantum-chemical study of the structure of N-substituted p-quinonimines and their reactions with hydrogen halides

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.

Halogenation of N-substituted p-quinone imines and p-quinone oxime esters: IV. Chlorination and bromination of N-arylsulfonyl-2(3)-methyl(2-chloro)-1,4- benzoquinone monoimines

The addition of halogens to N-arylsulfonyl-1,4-benzoquinone imines, which exist in a solution as Z and E isomers, is controlled by the steric factor. Z-E Isomerization strongly affects the stability of cyclohexene structures formed by halogenation of 1,4-
