Abstract
Disclosed is a method for producing an alicyclic alcohol represented by general formula (III) which is useful as a starting material for a flavor mixture or the like at low cost in high yield. The alicyclic alcohol represented by general formula (III) is produced by preparing a cyclohexanecarbonyl compound represented by general formula (II) through the carbonylation of an unsaturated hydrocarbon represented by general formula (I) (preferably a compound obtained through the partial reduction of a diene compound) using carbon monoxide in the presence of HF, and thereafter reducing the cyclohexanecarbonyl compound. In formulae (I), (II), and (III), Rrepresents an alkyl group having 1 to 4 carbon atoms, Rrepresents an alkyl group having 1 to 4 carbon atoms, Rrepresents an OH group, fluorine, or an ORgroup, and Rrepresents an alkyl group having 1 to 4 carbon atoms.
