Diazopropane (2) undergoes [3 + 2]-cycloaddition with 1-phenyl-bis-s-triazole[4, 3-b:3′,4′-f]pyridazine (1), which is a derivative of a heteroaromatic 14π-electron system, to give a 1:1 mixture of 11,11-dimethyl-6-phenyl-(3a) and 11,11-dimethyl-3-phenyl-11 H-pyrazolo[3,4-d]-bis-s-triazolo[4, 3-b:3′,4′-f]pyridazine (3b). These compounds represent derivatives of a novel heterocyclic system. The structures of the products were determined by independent syntheses.
