Versuchsvorschrift

A solution of biphenyl-4-carboxylic acid (9.9 g, 50 mmol) in 500 ml of ethanol and 150 ml of glacial acetic acid containing 1.0 g of platinum oxide was hydrogenated overnight at 40 psi. Upon filtering the solution and concentrating the filtrate under reduced pressure, 10.5 g of bicyclohexyl-4-carboxylic acid was obtained as a white solid (m.p. 122°-125° C.).
