Reactions of Polyhalogenated 4-Arylsulfonylimino-2-cyclohexenones and 3,6-Bis(arylsulfonylimino)cyclohexenes with Alcohols

Polyhalogenated 4-arylsulfonylimino-2-cylohexenones and 3,6-bis(arylsulfonylimino)cyclohexenes react with alcohols to give 1,2-addition products at the C=N bond through intermediate formation of N-arylsulfonylimino-p-quinonimines. Heating of the adducts above the melting point results in elimination of alcohol molecule and formation of quinoid structures.

Some Reactions of 4-Arylsulfonylimino-2,2,3,3-tetrachloro-1,2,3,4-tetrahydronaphthalen-1-ones

Reduction of 4-arylsulfonylimino-2,2,3,3-tetrachloro-1,2,3,4-tetrahydronaphthalen-1-ones with Zn/AcOH or Na2S2O4 results in elimination of two chlorine atoms with formation of benzoid structures.Reactions of the title compounds with dialkyl hydrogen phosp
