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