Abstract
Trifluoromethyl group substituted pyrazole derivatives were prepared from hydrazines and 1-aryl-3,4,4,4-tetrafluoro-2-buten-1-ones obtained by the deoxyfluorination of β-diketones. The reaction proceeded regioselectively and 5-aryl-3-trifluoromethyl-1-phenyl-1H-pyrazole was obtained from phenylhydrazine. On the other hand, when methylhydrazine was used, 3-aryl-5-trifluoromethyl-1-methyl-1H-pyrazole was selectively formed.
