Arenesulfinic acids react with 2,3,5,6-tetrachloro-N-arylsulfenyl-1,4-benzoquinonimines, following the 1,6-addition pattern. The reactions with excess arenesulfinic acid result in elimination of arenethiol and formation of 2,3,5,6-tetrachloro-4-arylsulfonylaminophenols. Oxidation of the latter yields 2,3,5,6-tetrachloro-N-arylsulfonyl-1,4-benzoquinonimines which are difficult to obtain by other methods.

The chlorination of p-arenesulfonamidophenols and N-(arylsulfonyl)-p-benzoquinone imines leads to 4--2,3,5,5,6,6-hexachloro-2-cyclohexen-1-ones.N-(Arylsulfonyl)-2,3,5,6-tetrachloro-p-benzoquinone imines were prepared for the first time.As a result of the occurrence of a competing hydrolysis process, in some cases, as well as chlorination products chloranil and/or 2,3,5,5,6,6-hexachloro-2-cyclohexene-1,4-dione were isolated.
