- Аннотация: For the first time 5,7-di-tert-butyl-1,3-dimethy1-3a,9a-diphenyl-3,3a-dihydro-1H-benzo[5, 6][1,4]clioxino [2,3-d]imidazol-2(9aH)-one 13 and complex 9 of 4,6-di-tert-butyl-3-nitrobenzene-1,2-diol with 1,3-dimethy1-4,5-diphenyl-1H-imidazol-2(3H)-one 10a were prepared by the reactions of 3-alkylthio-5,7-dimethy1-4a,7a-diphenyl-4a,5,7,7a-tetrahydro-1H-imidazo [4,5-e]-1,2,4-triazin-6(4H)-ones with 3,5-ditert-butyl-1,2-benzoquinone 1 and 4,6-di-tert-butyl-3-nitro-1,2-benzoquinone 2, respectively. Photochemical transformations of compounds 9 and 10a as well as products of its photooxygenation involving singlet oxygen under UV irradiation: urea 16, isomeric 1,3-dimethyl-4,5-diphenylimidazolidin-2-ones 17 and 17’, and compound 18 were studied by the spectral-kinetic method. Data on the absorption and fluorescence properties of synthesized compounds and their photoproducts were obtained. (C) 2018 Elsevier Ltd. All rights reserved.
