C(O[CH:4]1[CH2:9][CH2:8][CH2:7][CH2:6][C:5]1=[O:10])C.[CH:11]1([O:17]C(=O)CC)CCCC[CH2:12]1.[H][H]>[Pd]>[CH2:11]([O:17][O:10][C:5]1[CH:4]=[CH:9][CH:8]=[CH:7][CH:6]=1)[CH3:12]A solution of 10 gm. 2-ethoxycyclohexanone in 100 ml. cyclohexylpropionate was refluxed over 400 mg. of palladium on carbon until approximately 75% hydrogen had evolved. The catalyst was removed by filtration. O-ethoxyphenol was obtained in high yield.
