Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of 200 g of cuminic aldehyde, 200 g of 1,2-dimethoxy-ethane and 6 g of ruthenium -- 5% on charcoal; Doduco Chemie Werk, Sinsheim Elsenz, West Germany -- were heated in a stainless steel autoclave at 130° and at a pressure of 100 atm, for 25 h. The obtained reaction mixture was then filtered and subjected to a fractional distillation to yield 176 g (85%) of a 70 : 30 (parts by weight) mixture of cis and trans-4-isopropyl-cyclohexylmethanol. The obtained reaction mixture was then filtered subjected to a fractional distillation to yield

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 10 g of 4-isopropenyl-cyclohex-1-enylmethanol dissolved in 200 ml of ethanol were hydrogenated at atmospheric pressure in the presence of 200 mg of Raney nickel. The reaction mixture was then filtered, evaporated and finally subjected to a fractional distillation. It was thus isolated a product having bp 75° - 115°/10 Torr. The vapour phase chromatography analysis showed that the isolated product contained 50% of a 60 : 40 (parts by weight) mixture of cis and trans isomers of the desired alcohol. The reaction mixture was then filtered evaporated finally subjected to a fractional distillation It was thus isolated a product
