Abstract
Prodn. of cis-4-tert.-butyl-cyclohexanol by catalytic hydrogenation of 4-tert.-butyl-cyclohexanone-1 is improved by using a Raney nickel or Raney cobalt catalyst, and carrying out the reaction in 1-5C alcohol as a solvent at a temp. below 50 degrees C (pref. from -10 degrees to +30 degrees C) under an elevated press., pref. in the presence of an alkali hydroxide or alkali alcoholate, the acetate of cis-4-tert.-butyl-cyclohexanol is used widely in the perfumery industry (scent with wood-like miance). The product of the above reaction consists predominantly of the cis-isomer (the known processes yield mainly the less valuable trans-isomer).
