Popis:	By1H and19F NMR spectroscopy it was shown that reaction of fluoroalkyl β-ketoesters with methylhydrazine in deuteromethanol at −30 to 30‡C involves intermediate formation of the β-ketoester salts with methylhydrazine and 3,5-dioxypyrazolidines which successively split off methanol and H2O with formation of 3-oxypyrazolines and pyrazol-5-ones, respectively.
