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

Avdeenko, A. P.,Zhukova, S. A.

, p. 423 - 427 (2007/10/03)

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.
