1,3-Dipolar Cycloadditions of 2-Diazopropane to 1-Phenyl-bis-s-triazolopyridazine. The Synthesis of 11,11-Dimethyl-11H-pyrazolobis-s-triazolopyridazines, Derivatives of a Novel Heterocyclic System

Diazopropane (2) undergoes -cycloaddition with 1-phenyl-bis-s-triazolepyridazine (1), which is a derivative of a heteroaromatic 14?-electron system, to give a 1:1 mixture of 11,11-dimethyl-6-phenyl- (3a) and 11,11-dimethyl-3-phenyl-11H-pyrazolo-bis-s-triazolopyridazine (3b).These compounds represent derivatives of a novel heterocyclic system.The structures of the products were determined by independent syntheses.
