Abstract

Radical intermediates formed at 25°C in the presence and absence of oxygen during the photolysis of anthraquinone in aromatic, cyclic and aliphatic hydrocarbon solvents were trapped by 2,6-dichloronitrosobenzene, 2,6-dibromonitrosobenzene and 2,4,6-tribromonitrosobenzene. The resulting nitroxide radicals have been characterized “in situ” by ESR spectra.

Abstract

С помощью спиновых ловушек: 2,6-дихлорнитрозобензола, 2,6-дибромнитрозовензола и 2,4,6-трибромнитрозобензола—были обнаружены промежуточные радикалы, образующиеся в присутствии и отсутствии кислорода при фотолизе антрахинона в растворах ароматических, алифатических и циклических углеводородов при температуре 25°C. Образовавшиеся радикалы были охарактеризованы по их спектрам непосредственно в резонаторе ЭПР.
