Abstract
2,3-Di(2-azulenyl)pyrazines and -quinoxalines were obtained by the reaction of di(2-azulenyl)ethanedione with diamines. Cyclodehydrogenation reaction of the pyrazine and quinoxaline derivatives with manganese dioxide afforded the corresponding azulene-fused quinoxaline and phenazine derivatives, respectively.
