ABSTRACT:
4-tert.-Butylcyclohexanol having a larger content of its cis-isomer is prepared by hydrogenating 4-tert.-butylphenol in a solvent in the presence of a rhodium catalyst and a compound selected from the group consisting of hydrogen chloride and (anhydrous) sulfuric acid. Furthermore, 4-tert.-butylcyclohexanol obtained by the above hydrogenation is acetylated to give 4-tert.-butylcyclohexyl acetate.
