Abstract:
Twenty-five pyrazolones were prepared by reacting mono- or disubstituted cyanoacetic esters with hydrazine, phenylhydrazine and semicarbazide. 4-Benzyl-3-amino-1-phenyl-5-pyrazolone has been synthesized and its properties have been compared with those of the corresponding 2-phenylpyrazolone derivative. The ultraviolet absorption spectra of several pyrazolones have been determined.
