Hlouskova, Zuzana published the artcileSynthesis and properties of push-pull imidazole derivatives with application as photoredox catalysts, Computed Properties of 596819-12-4, the publication is ARKIVOC (Gainesville, FL, United States) (2017), 330-342, database is CAplus.
Two new push-pull mols. with imidazole-4,5-dicarbonitrile acceptor, thiophene and 2-methoxythiophene donors with potential use in photoredox catalysis were designed and prepared The synthesis started from com. available imidazole-4,5-dicarbonitrile and its bromination and N-methylation. Subsequent Suzuki-Miyaura cross-coupling with (5-methoxy)thiophene-derived boronic acids afforded target push-pull derivatives Beside common anal. methods, the mol. structure of 5-methoxythiophen-2-yl derivative has also been verified by X-ray anal. DSC analyses showed remarkable thermal stabilities of both target derivatives with Tm and TD values above 150 and 270°C, resp. Fundamental properties and extent of the intramol. charge-transfer were further studied by UV-VIS absorption spectra and DFT calculations Fundamental photoredox properties of target imidazole derivatives were elucidated. Both push-pull mols. were preliminary tested as photoredox catalysts in cross-dehydrogenative coupling reaction between tetrahydroisoquinoline and nitromethane and the results were compared with those obtained by pyrazine-2,3-dicarbonitrile-derived catalyst.
