dc.description.abstract | 2,3-Dicyano-5,7-bismethylthieno[3,4-b]pyrazine (5), has been obtained as a
minor product from reactions of S-nucleophiles with 5,6-di(1-bromoethyl)pyrazine-2,3-
dicarbonitrile (3), or from a condensation of 4-hydroxy-2,5-dimethyl-2,3-dihydrothiophen-
3-one (4) with diaminomaleonitrile. The molecular structure of compound 5 has been
confirmed by X-ray diffraction. A partial separation of charge causes a donor-acceptor
type arrangement of the planar molecules in uniform parallel stacks with an interplanar
spacing of 3.334(2) Å at 100 K. | nb_NO |
