Og. Kuzueva et al., SYNTHESIS OF 2-ARYLHYDRAZONES OF ALIPHATIC FLUORINE-CONTAINING 1,2,3-TRICARBONYL COMPOUNDS AND THEIR REACTIONS WITH DINUCLEOPHILES, Russian chemical bulletin, 47(4), 1998, pp. 673-678
New fluorinated 2-arylhydrazones of 1,2,3-tricarbonyl compounds were o
btained by coupling fluorine-containing S-oxo esters, 1,3-diketones, a
nd their copper chelates with aryldiazonium chlorides. Reactions of th
ese arylhydrazones with hydrazine hydrate, phenylhydrazine, thiosemica
rbazide, and hydroxylamine gave the corresponding pyrazole and isoxazo
le derivatives.
