4-tert-Butylcyclohexanone Usage And Synthesis |
Chemical Properties | WHITE TO ALMOST WHITE CRYSTALLINE POWDER |
Occurrence | Has apparently not been reported to occur in nature. |
Uses | 4-tert-Butylcyclohexanone is used as a perfuming agents and in cosmetic. |
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°. |

Purification Methods | Purify it via the semicarbazone (crystallised from EtOH with m 203-205o), hydrolyse this with dilute HCl and steam distil it. The distillate is extracted into Et2O, dried, evaporated and the residue is recrystallised from pentane, aqueous EtOH or EtOH [Houlihan J Org Chem 27 3860 1962]. The oxime recrystallises from 1,2-dichloropropane and has m 137.5-138.5o. [Harvill et al. J Org Chem 15 58 1950, Beilstein 7 IV 82.] |
