3-Phenylpyrazole-5-diazonium chloride (2) couples with benzoylacetonitrile and with phenacylthiocyanate to yield the corresponding hydrazone derivatives 3 a, b. Whereas 3 a cyclised into the pyrazolo[1,5-c]-as-triazine derivative (4a) upon treatment with concentrated sulphuric acid via elimination of water, treatment of 3 b with the same reagent under the same conditions has resulted in elimination of thiocyanic acid and the formation of the pyrazolo[1,5-c]-as-triazine derivative (4b).
