Participants

Reaction Steps

A solution of 0.7 g of 1,8-difluoro-2,7-dioctyloxyphenanthrene in 50 ml of THF hydrogenated at atmospheric pressure at 20° C. with addition of 0.1 g of Pd/C (5% by weight). The catalyst is filtered off, the solvent is removed by vacuum distillation, and the residue is chromatographed on silica gel using dichloromethane. Recrystallization from acetonitrile gives 0.4 g of 1,8-difluoro-2,7-dioctyloxy-9,10-dihydrophenanthrene.
