Reaktionsschritte
First, 3 g of 16-bromo-1-hexadecanol, 1.9 g of 2,3-difluoro-4'-hydroxybiphenyl, 2.6 g of potassium carbonate, and 50 ml of methyl ethyl ketone were placed in a 100 ml flask. The reaction mixture was stirred under reflux for 32 hours. The reaction mixture was poured into water, and an organic layer was extracted with ether. The ether layer was washed with water and dried over anhydrous sodium sulfate. Thereafter, the solvent was distilled away. The residue was recrystallized from acetone to obtain 3.5 g of 2,3-difluoro-4'-(16-hydroxyhexadecyl)oxybiphenyl (Y: 84%). The compound thus obtained had a purity of 97.4% by GC.
