Abstract
Fluoroalkyl β-alkyl-β-aminovinyl ketones react with hydrazine hydrate to give the respective razoles and with phenylhydrazine they form a mixture of pyrazoles and 5 hydroxy-δ2-pyrazolines. Alkyl(aryl) β-fluoroalkyl-β-aminovinylketones do not react with the hydrazines mentioned above. With 2,4-dinitrophenylhydrazine, both types of fluoroalkyl-containing β-aminovinyl ketones give only hydrazones of the corresponding methyl alkyl(aryl) ketones.
