An unexpected valence bond isomerization to the heteroaromatic ring system: [1,2,3]triazolo[4,5-d]pyridazine
Abstract
The arylazo substituted salt 2 when treated with a base underwent a valence bond isomerization to yield a derivative of the heteroaromatic ring system, [1,2,3]triazolo[4,5-d]pyridazine (4).
