Reaction of N-Arylsulfonyl-p-quinonimines and semiquinoid structures produced therefrom with Bis(p-dimethylaminophenyl)phosphinite

N-Arylsulfonyl-1,4-benzoquinonemonoimines react with bis(N-dimethylaminophenyl)phosphinite in keeping with the character and position of substituents in the quinoid ring along 1,4-, 6,1-, or 1,2-addition way; N-arylsulfonyl-1,4-naphthoquinonemonoimines react along 1,4-, 6,1-, 1,2-, or 6,3-addition. Semiquinoid polyhalostructures generated therefrom react similarly to the corresponding quinonimines possessing several chlorine substituents in the quinoid ring. N,N-Diarylsulfonyl-1,4-benzoquinonediimines with no substituents in the ring yield with bis(p-dimethylaminophenyl)phosphinite 1,4-addition products. Along a competing reaction quinonediimine is reduced to the corresponding phenylenediamine. With the tetrachloro substituted in the ring 1,4-benzoquinonediimine and the corresponding semiquinoid derivative only reduction is observed.
