Goncharova S. The syntesis, structure and reaction of polyhaloid halfqunoid structure on the basis of N-arylsulfonyl-p-quinoneimines and ether of p-quinonemonooximes

The dissertation is dedicated to investigation of synthesis, structure and reacting abilities of polyhaloid halfquinoid structures on the basis of N-arylsulfonyl-p-quinoneimines and 4-aroyl(arylsulfonyl)oxiimino-2,5-cyclohexadien-1-ones with one or two halogen atoms at sp3-hybridizating carbon atoms. It was discovered, that in case primary proceeding of reaction dehydrohalogenation, reaction of polyhaloid halfqinoid structures on the basis of N-arylsulfonyl-p-quinoneimine with arylsulfinic and hydrazoic acids, tozylhidrazine, dialkylphosphites, alcohols is proceeding by analogy with corresponding quinoneimines. It is proved trans-addition of halogen to quinoneimines with formation of halfquinoid compounds by priority diacsial location of halogen atoms. It is set, that direction of addition of halogens to ethers 1,4-benzoquinonemonooximes is conditiones by the structure of the latter. The mechanism of halogenation is offered. Regiospesific is proved. It is offered the mechanism of ehydrohalogenation of polyhaloid halfquinoid compounds, which have one proton in both sp3-hybridizating carbon atoms.
