1,1,1,2,2-pentafluoro-6,6-dimethylheptane-3,5-dione

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: At room temperature, hydrazine hydrate (2.06 g) is added to a solution of 1,1,1,2,2-pentafluoro-6,6-dimethylheptane-3,5-dione (10.1 g) in ethanol (100 ml). The reaction mixture is stirred at room temperature overnight. After removal of the solvents under reduced pressure, 3-tert-butyl-5-(pentafluoroethyl)-1H-pyrazole (7.9 g, 79%) is obtained. After removal of the solvents under reduced pressure
