Synthesis of 5,12-Diazapentacenes and Their Properties
An efficient synthesis via a precursor route to a new class of linear dialkyldiaminoazapentacenes is reported. The synthetic route involves the coupling of 4-substituted aniline derivatives to 2,5-dibromoterephthalonitrile via Buchwald–Hartwig amination followed by an acid-mediated cyclization to fu...

| Zusammenfassung: | An efficient synthesis via a precursor route to a new class of linear dialkyldiaminoazapentacenes is reported. The synthetic route involves the coupling of 4-substituted aniline derivatives to 2,5-dibromoterephthalonitrile via Buchwald–Hartwig amination followed by an acid-mediated cyclization to furnish the diazapentacenes. These reactions occur under short reaction times ( |
