Abstract:

The two new tetrakis-substituted pyrazines, 1,1′,1′′,1′′′-(pyrazine-2,3,5,6-tetrayl) tetrakis(N,N-dimethylmethanamine), C16H32N6, (I) and N,N′,N′′,N′′′-[pyrazine-2,3,5,6-tetrayltetrakis(methylene)]tetrakis(N-methylaniline), C36H40N6, (II), both crystallize with half a molecule in the asymmetric unit; the whole molecules are generated by inversion symmetry. There are weak intramolecular C—H...N hydrogen bonds present in both molecules and in (II) the pendant N-methylaniline rings are linked by a C—H...π interaction. The degredation product, N,N′-[(6-phenyl-6,7-dihydro-5H-pyrrolo[3,4-b]pyrazine-

Abstract:

2,3-Diphenylated quinoxaline, pyrido[2,3-b]pyrazine and 8-bromopyrido[3,4-b]pyrazine were halogenated in deprotometalation-trapping reactions using mixed 2,2,6,6-tetramethyl piperidino-based lithium-zinc combinations in tetrahydrofuran. The 2,3-diphenylated 5-iodo- quinoxaline, 8-iodopyrido[2,3-b]pyrazine and 8-bromo-7-iodopyrido[3,4-b]pyrazine thus obtained were subjected to palladium-catalyzed couplings with arylboronic acids or anilines, and possible subsequent cyclizations to afford the corresponding pyrazino[2,3-a]carbazole, pyrazino[2′,3′:5,6] pyrido[4,3-b]indole and pyrazino[2′,3′:4,5]p

Abstract:

Two pyrido[2,3-b]pyrazines were isolated from the extract of the springtail Tetrodontophora bielanensis (WAGA). Their structure were determined by mass and NMR spectroscopy: 2,3-dimethoxypyrido[2,3-b]pyrazine (I) and 2-methoxy-3-isopropylpyrido[2,3-b]pyrazine (II).

Abstract:

The synthesis of a new dialkyl-functionalized quinoxaline acceptor, 5,8-dibromo-2,3-dihexylquinoxaline, is reported, along with its cross-coupling with 2,3-dihexylthieno[3,4-b]pyrazine via direct arylation polymerization. The resulting ambipolar-acceptor polymer poly(2,3-dihexylthieno[3,4-b]pyrazine-alt-2,3-dihexylquinoxaline) exhibits a low bandgap of 1.07 eV and high solubility. The results of initial organic photovoltaic devices are also reported.
