Abstract
3-Amino-5-pyrazolones did not react with guanidine in aqueous solution, but with aldehydes in the presence of piperidine, the amino group was removed in some cases. 5-Pyrazolonoguanidines were synthesized by the direct fusion of 3-amino-5-pyrazolones and dicyandiamide. The infrared spectra of the pyrazolone derivatives prepared are briefly discussed.
