Benzotriazol-1-yl-acetone as a Building Block in Heterocyclic Chemistry: a Route to Benzotriazolylpyridazines, Benzotriazolylphthalazines and Benzotriazolylpyrazolo[5,1-c]-1,2,4-triazines
Abstract
Benzotriazolylacetone is coupled with aromatic diazonium salts to yield arylhydrazones, which can be condensed with ethyl cyanoacetate yielding pyridazinones whose reactivity towards activated double bond systems is investigated.
