Ethanol → 8-(4-Propylphenyl)-1,4-dioxaspiro[4.5]decane

Participants

Reaction Steps

To a mixed solution comprising 250 ml of ethanol and 250 ml of toluene was dissolved 80 g of the 1,1-ethylenedioxy-4-(4-n-propylphenyl)-4-cyclohexene, 5 g of palladium/carbon (5%) was added as catalyst thereto, and subjected to a catalytic reduction under hydrogen gas atmosphere. After finishing of the reaction, the catalyst was filtered off and the solvent was distilled off under a reduced pressure to obtain 84 g of 1,1-ethylenedioxy-4-(4-n-propylphenyl)cyclohexane.
