Sambursky S. Synthesis and properties of ketals of 5-substituted of acenaphthenequinones

The thesis is devoted to the development of selective protecting of carbonyl groups of 5-halogensubstituted acenaphthenequinones, as well as to the revealing of distinctive features, which are characteristic for isomeric compounds, and the study of their chemical behaviour in basic media. Various synthones of 5-substituted acenaphthenequinones have been synthesized. The possibility of their use as substrates for the nucleophilic aromatic replacement has been illustrated by reaction of methoxydehalogenation as an example. The experiments on investigation of the 1-oxo-5-bromomonoketal of 5-bromoacenaphthenequinone and 5-chloroacenaphthenequinone bisketal 1,4-dioxane types arylation have been carried out. Sphere of use: chemistry.
