Due to these effects, the main heavy product of radiolysis at 295 K is 4-oxopent-2-en-2-yl acetate. Under boiling conditions (413 K), hydrogen bonds are eliminated, leading to the predominant formation of 4-hydroxy-2-pentanone, which is not detected at 295 K.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45181324393264">На примере ацетилацетона показано, что внутримолекулярная водородная связь существенно влияет на радиолитические превращения органических соединений, подавляя перенос протона от первичного катион-радикала к молекуле, а также способствуя разрыву С–ОН-связи в енольной форме. Вследствие этих эффектов основным тяжелым продуктом радиолиза при 295 К является 4-оксопент-2-ен-2-илацетат. В условиях кипения (413 К) водородные связи разрушаются, что приводит к преобладающему образованию 4-гидрокси-2-пентанона, который не обнаруживается при 295 К.</p></trans-abstract><kwd-group xml:lang="en"><kwd>acetylacetone</kwd><kwd>tautomers</kwd><kwd>hydrogen bond</kwd><kwd>radiolysis</kwd><kwd>proton transfer</kwd><kwd>radical recombination</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>ацетилацетон</kwd><kwd>таутомеры</kwd><kwd>водородная связь</kwd><kwd>радиолиз</kwd><kwd>перенос протона</kwd><kwd>рекомбинация радикалов</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы выражают благодарность Центру коллективного пользования физико-химическими методами исследований Института физической химии и электрохимии РАН за предоставленное оборудование.</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Belova N.V., Oberhammer H., Trang N.H., Girichev G.
