4-tert-Butylcyclohexanone Usage And Synthesis
Chemical Properties WHITE TO ALMOST WHITE CRYSTALLINE POWDER
Occurrence Has apparently not been reported to occur in nature.
Preparation By hydrogenation of p-ferr-butylphenol. Care must be taken that no free p-tert-butylphenol remains, because it is a sensitizer and depigmenting agent(Opdyke, 1974).
Preparation N-Chlorosuccinimide (NCS) (8.0 g, 0.060 mol) and toluene (200 mL) were cooled to 0 C° in a 1-L, threenecked, round-bottomed flask equipped with a mechanical stirrer, a thermometer, a dropping funnel, and an argon inlet tube. Dimethyl sulfoxide (6.0 mL, 0.10 mol) was added and the mixture was cooled to -25 C° using a tetrachloromethane/dryice bath. A solution of 4-tert-butylcyclohexanol (6.24 g, 0.04 mol; mixture of E and Z isomers) in toluene (40 mL) was added dropwise over 5 min, stirring was continued for 2 h at -25 C°, and then a solution of triethylamine (6.0 g, 0.06 mol) in toluene (10 mL) was added dropwise over 3 min. The cooling bath was removed, and, after 5 min, diethyl ether (400 mL) was added. The organic phase was washed with 1% aq. hydrochloric acid (100 mL) and then with water (2 × 100 mL), and dried over anhydrous magnesium sulfate. The solvents were evaporated under reduced pressure, and the residue was transferred to a 50-mL, round-bottomed flask and bulb-to-bulb distilled at 120 C° (25 mmHg) to yield 5.72 g (93%) of 4-tertbutylcyclohexanone 1794; mp 41–45 C°. Recrystallization from petroleum ether at -20 C° gave an 88% recovery of 1794 with mp 45–46 C°.
