Chlorination and bromination of N-arylsulfonyl-1,4-benzo(naphtho)quinonimines, N,N'-bis(arylsulfonyl)-1,4-benzoquinonediimines, N-arylsulfonyl-4-aminophenols, and N-arylsulfonyl-4-aminonaphthols gave a number of stable polyhalogenated structures containing hydrogen at the sp3-hybridized carbon atoms. The chlorination and bromination schemes of N-arylsulfonyl-p-quinonimines are discussed.

2,3,6-Tribromo-N-phenylsulfonyl-1,4-benzoquinon-4-imines are formed on bromination of 4-arenesulfonamidophenols and N-aryl-sulfonyl-1,4-benzoquinon-4-imines but 2-bromo-N-arylsulfonyl-1,4-naphthoquinon-4-imines are formed from 4-arenesulfonamido-1-naphthols and N-arylsulfonyl-1,4-naphthoquinon-4-imines.

In the reaction of hydrogen bromide with N-(p-tolyl)-1,4-benzoquinone monoimines bromination of the p-tolyl fragment takes place as well as nucleophilic addition.Bromination is fully suppressed by the addition of resorcinol to the reaction mass.In the case of N-(p-tolylsulfonyl)-1,4-benzoquinone monoimine the products from the entry of two bromine atoms at the ortho position to the oxygen atom are formed sucessively.
