1-Aminopyrazolin-5-ones. Synthesis and reactivity

A synthesis of 1-aminopyrazolin-5-ones (I) by chloramine attack on the 2-benzylpyrazolones (IV d-e) has been accomplished.Nucleophilic substitution reactions of aminopyrazolones (I) are investigated; with 1,4-diketones, N,N'-pyrrolylpyrazolones (XVIIa-c)
