Rusinov, O. N. Chupakhin // ARKIVOC. - 2004. - № 12. - P6-13. - Библиогр. : с. 12 (13 назв.) Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: A method of direct C-C coupling of azahetarenes with macrocycles (calix[4]arene, benzo-12-??crown-4, 1,5-bis(2,6-dimethylphenoxy)-3-oxapentane), based on the nucleophilic addition to ??unsubstituted carbon atom in azines, has been developed. |
