Versuchsvorschrift

146 g (0.392 mol) of 3,3′-dibenzyloxybiphenyl are dissolved in 1.5 I of THF and hydrogenated to completion on a Pd/C catalyst. The catalyst is filtered off, the filtrate is evaporated, and the residue is filtered through silica gel with toluene/ethyl acetate, giving biphenyl-3,3′-diol as a colourless solid.
