反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 85 g 4-(3-methyl-but-2-enyl)-phenol, 3 wt. % rhodium-on-active charcoal (Rh content, based on the weight of the dry catalyst: 5%; wafer content about 50%) are initially introduced into 300 ml cyclohexane in a stirred autoclave with a gassing stirrer. Hydrogenation is carried out for 5 hours at 100° C. under a hydrogen pressure of 20 bar. After filtration, 85 g 4-isoamylcyclohexanol are obtained as a crude product. After distillation, 80 g 4-isoamylcyclohexanol, which has the following composition: 50.4% cis-4-isoamylcyclohexanol and 49.1% trans-4-isoamylcyclohexanol, are obtained. After filtration, 85 g 4-isoamylcyclohexanol are obtained as a crude product After distillation, 80 g 4-isoamylcyclohexanol, which
