| Abstract: | New fluorinated 2-arylhydrazones of 1,2,3-tricarbonyl compounds were obtained by coupling fluorine-containing 3-oxo esters, 1,3-diketones, and their copper chelates with aryldiazonium chlorides. Reactions of these arylhydrazones with hydrazine hydrate, phenylhydrazine, thiosemicarbazide, and hydroxylamine gave the corresponding pyrazole and isoxazole derivatives.
