Reaction Conditions

Reaction Steps

5% Rh/C (450 mg, 15% w/w) was charged into a 50 mL autoclave vessel containing a mixture of 2,2-dimethyl-3-(3-methylphenyl)propan-1-ol (6 g, 34 mmol) in water (17 mL). The mixture was vigorously stirred under an hydrogen atmosphere (10 Bar) at 60° C. for 6 h. The reaction mixture was filtered and the filtrate was extracted with MTBE (25 mL), dried over magnesium sulphate and concentrated. The resulting crude product was distilled with a bulb-to-bulb distillation (2.5 mBar, 90° C.) to give 2,2-dimethyl-3-(3-methylcyclohexyl)propan-1-ol (5.1 g, gc purity>99%; yield 82%).
