Geometrical Analogues of Purine Substrates (5-Methyladenine, Pyrolysis, Diazabiphenylene)

Synthetic approaches are developed to cyclobutadienopurines and lin-benzocyclobutadienopurines, new extended purine analogues, by means of flash vacuum pyrolysis of suitable condensed pyridazine precursors. As a model for the cyclobutadienopurine ring system, benzo{3,4}cyclobutadieno{1,2-d}imidazole was prepared by thermal extrusion of dinitrogen. As expected of biphenylene analogues with increased electron density in the four-membered ring, the benzocyclobutadienoimidazole underwent extensive decomposition.
