Заглавие : A new route towards dithienoquinazoline and benzo[f]thieno[3,2-h]quinazoline systems using Pd-catalyzed intramolecular cyclization under microwave irradiation [Электронный ресурс] Место публикации : ARKIVOC. - 2016. - № 4. - С. 204-216 Систем. требования: http://apps.webofknowledge.com/full Примечания : 1.11.16 ББК : 54 Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ Ключевые слова (''Своб.индексиров.''): pyrimidines --intramolecular cyclizations --fused ring systems--thienoacenes Аннотация: A novel synthetic route to novel thienoacene systems bearing a fused pyrimidine ring is proposed. The commercially available 5-bromopyrimidine is used as the starting material to obtain various dithienoquinazoline and benzo[f]thieno[3,2-h] quinazoline systems through the Suzuki cross-coupling, nucleophilic aromatic substitution of hydrogen (the S-N(H) reaction), and finally palladium-catalyzed intramolecular cyclization under microwave irradiation. Redox properties of some of the new compounds have been investigated. The data obtained show that these systems have plausible potential for use in organic electronic applications.
