Konovalova S. The halogenation of alkylsubstituted in quinoid ring N-arylsulfonyl-1,4-benzoquinonemonoimines and 4-aroyl(arylsulfonyl)oximino-2,5-cyclohexadien-1-ones.

The object of investigation is the N-arylsulfonyl-1,4-benzoquinonemonoimines and 4-aroyl(arylsulfonyl)oximino-2,5-cyclohexadien-1-ones. The purpose of the thesis is the recognizing of the common rules of halogenation of N-arylsulfonyl-1,4-benzoquinonemonoimines and 4-aroyl-(arylsulfonyl)oximino-2,5-cyclohexadien-1-ones. The process of halogenation of N-arylsulfonyl-1,4-benzoquinonemonoimines and 4-aroyl(arylsulfonyl)oximino-2,5-cyclohexadien-1-ones has been investigated. The common rules of these reactions have been clearly recognized. The configuration of nitrogen atom isn't changed when the halogenation of 4-aroyl(arylsulfonyl)oximino-2,5-cyclohexadien-1-ones is proceeded. The proof of existence of prototropic rearrangement of cyclohexenic compounds has been obtained. The products of the halogenation of N-arylsulfonyl-1,4-benzoquinonemonoimines and 4-aroyl(arylsulfonyl)oximino-2,5-cyclohexadien-1-ones - the halfquinoid compounds can be separated to optical isomers.
