Reaction of 2,3,4-pentantrione-3-arylhydrazones with N,N-dimethylhydrazine: Formation of substituted 1H-pyrazoles via demethylation

Article abstract of DOI:10.1080/00397919209409257

A novel one-step synthesis of 4-arylazo-1H-1,3,5-trimethylpyrazoles is accomplished by reaction of N,N-dimethylhydrazine with2,3,4-pentantrione-3-arylhydrazones via an unusual demethylation.
