Abstract
Results of oxidation 2-(N-acetylamine)-3-(3,5-di- tert -butyl-4-hydroxyphenyl)-propionic acid oxygen depend on temperature. At 55 ℃ - 60 ℃ , 2,4-di- tert -butylbicyclo(4,3,1)deca-4,6-dien-8-(N-acetylamine)-3,9-dion-1-oxa is formed. The constitution is based on dates of spectrums 1Н and 13С NMR. At 95 ℃ - 97 ℃ , mixtures of 2,4-di- tert -butylbicyclo(4,3,1)deca-4,6-dien-8-(N-acetylamine)-3,9-dion-1-oxa and of 6,8-di- tert -butyl-3-(N-acetylamine)spiro(4,5)deca-1-oxa-5,8-dien-2,7-dione are produced. Structures are calculated by the method of Hartrii-Foka. Values of enthalpies and of entropies allow to assume dynamic isomerism.
