Reaction of N-arylsulfonyl-p-quinonimines and semiquinoid compounds derived therefrom with arylsulfinic acids

N-Arylsulfonyl-2,3,5,6-tetrachloro-1,4-benzoquinonimines and 4-arylsulfonylimino-2,3,5,6,6-pentachloro-2-cyclohexen-1-ones react with arylsulfinic acids regioselectively along 6,1-addition. With 4-arylsulfonylimino-2,3,5,6,6-pentachloro-2-cyclohexen-1-ones the 6,1 addition is preceded by nucleophilic substitution of chlorine in position 2. With N-arylsulfonyl-2,3-dichloro-1,4-naphthoquinonimines, 4-arylsulfonyl-2,2,3-trichloro-1,2,3,4-tetrahydronaphthalen-1-ones and 4-arylsulfonyl-2,2,3,3-tetrachloro-1,2,3,4-tetrahydronaphthalen-1-ones occurred nucleophilic substitution of chlorine in position 2 followed by 6,1-addition of arylsulfinic acid molecule.

NUCLEOPHILIC SUBSTITUTION IN THE SERIES OF N-ARYLSULFONYL-1,4-NAPHTHOQUINONE MONOIMINES

The reactions of 2-substituted N-arylsulfonyl-1,4-naphthoquinone monoimines with arenesulfinic acids, amines, sodium methoxide, and the p-toluenesulfonamide sodium salt were investigated.The effect of the substituent at position 2 of the quinone imine on
