Hydrazine adds to allenic or acetylenic nitriles to give 3-alkyl-substituted 5-aminopyrazoles in excellent yields. Conjugated and unconjugated enaminic nitriles may be isolated from the Michael addition of phenylhydrazine to allenic nitriles and ring-closed to give 3-alkyl-5-amino-N-phenylpyrazoles and 3H-indoles.
