Versuchsvorschrift

A solution of 100 mg of 4-hydroxy-4-trifluoromethyl -2,5-cyclohexadien-1-one in 1 mL of absolute ethanol was treated with a few mg of 5% palladium on carbon, hydrogenated in a Parr shaker for one hour under 50 psig of hydrogen, and filtered. Gas chromatographic/mass spectral analysis indicated that the major component of the filtrate was 4-hydroxy-4-trifluoromethylcyclo hexanone: mass spectrum (70 eV) m/z (relative intensity) 182 (11, M+), 55 (100), 42 (40).
