(1, 3, 4, 6, 8, 9b-hexaazaphenalene) are reported. The syntheses were abbreviated in that they consisted of a two-step procedure whereby the appropriate diaminoazine was treated with methyl N-cyanomethanimidate and NaOMe in MeOH to give the corresponding bis (N'- cyano-N-formamidino) azines and these were subjected to short vacuum pyrolysis to afford the azacyc1 [3.3. 3] azines. The valence orbital electronic structure of this series of ...
