Abstract
The reactions of 5,6-dichlorofurazano[3,4-b]pyrazine with phenyl- and methylhydrazines were studied in order to prepare furazano[3,4-b]pyrazine derivatives potentially capable of being oxidized to paramagnetic derivatives. The synthesis of new polyheterocyclic compounds containing the furazano[3,4-b]pyrazine structural moiety annulated to the tetrazine or triazole ring is described. The structures of all compounds were confirmed by X-ray diffraction.
