It has been shown that pyrazoles (hydroxypyrazoles) are formed upon reaction of fluorine-containing copper β-diketonates (β-ketoesterates) with hydrazines and their hydrochlorides.A preparative method has been developed for the synthesis of fluorinated pyrazoles and hydroxypyrazoles via treatment of fluorine-containing β-diketonate and β-ketoesterate copper compounds with hydrazines.The molecular structure of 1-phenyl-3-octafluorobutyl-5-hydroxypyrazole has been established based on x-ray structural analysis.
