Abstract
The catalytic hydrodenitrogenation of model heterocyclic nitrogen compounds such as carbazole, tetrahydro-and hexahydrocarbazoles has been studied. The results indicate that the hydrodenitrogenation was complete in the case of tetrahydro- and hexahydrocarbazoles and almost complete in the case of carbazole. Rate constants for the first two compounds were 3 times higher than for carbazole. The mechanistic consequences of these results are discussed.
Abstract
Исследовали каталитическое гидродеазотирование таких модельных гетероциклических азотных соединений, как карбазол, тетрагидро- и гексагидрокарбазолы. Гидродеазотирование было полностью завершено в случае тетрагидро- и гексагидрокарбазолов и почти завершено в случае карбазола. Константы скорости для двух первых соединений в 3 раза превышают константу скорости для карбазола. Обсуждаются механистические последствия этих результатов.
