Procedure
2-Phenoxy-cyclohexanol (13.64 g, 0.071 mol) was dissolved in acetone (260 mL), cooled to between 0° C. to 5° C., and Jones Reagent (2 M, 78 mL) was added dropwise. The reaction was stirred for 4.5 hours. The reaction mixture was poured into water (250 mL), and diethyl ether (500 mL) was added. The organic phase was separated from the aqueous phase, then washed with water, dried (over MgSO4), and concentrated to yellow crystals. The crystals were recrystallized from pentane to give 2-phenoxy-cyclohexanone (a compound of general Formula III) (10.22 g, 76%). 1 HNMR (CDCl3): δ7.2 (m, 2H), 7.0 (m, 2H), 6.8 (d, 1H), 4.6 (m, 1H), 2.6 (m, 1H), 2.4 (m, 2H), 2.0-1.8 (m, 5H) ppm.
