39.1% With sodium carbonate;tetrakis(triphenylphosphine) palladium(0); In ethanol; water; benzene; for 48h;Heating / reflux; (5-a) Synthesis of compound 4-bromo-2,6-difluoro-4'-(trans-4-pentylcyclohexyl)biphenyl represented by formula: First, 50 ml of ethanol containing 5.61 g of 4-(trans-4-pentylcyclohexyl)phenylboronic acid dissolved therein, 50 ml of benzene containing 5.0 g of 4-bromo-2,6-difluoro-1-iodobenzene dissolved therein, 15.7 ml of a sodium carbonate aqueous solution with a concentration of 2.0 mol/l, and 0.45 g of tetrakis(triphenylphosphine)palladium(0) were put in an argon-replaced 200 ml flask, and stirred under reflux for 48 hours.. After the reaction, water and ether were added to the reaction solution for extraction.. The resultant ether layer was washed with a saturated brine and dried with sodium sulfate.. The solvent was then distilled off.. The residue was purified by silica gel column chromatography (eluent:hexane) and recrystallized from acetone, to obtain 2.58 g (Y: 39.1%) of 4-bromo-2,6-difluoro-4'-(trans-4-pentylcyclohexyl)biphenyl.. The purity of the resultant compound was 100.0% as measured by GC. (5-b) Synthesis of polymerizable compound 2,6-difluoro-4'-(trans-4-pentylcyclohexyl)-4-vinylbiphenyl represented by formula (E) above First, 2.58 g of 4-bromo-2,6-difluoro-4'-(trans-4-pentylcyclohexyl)biphenyl obtained from the synthesis (5-a) above, 2.33 g of tributylvinyltin, 0.18 g of tetrakis(triphenylphosphine)palladium(0), 0.008 g of p-methoxyphenol, and 50 ml of anhydrous toluene were put in an argon-replaced 300 ml flask, and stirred under reflux for nine hours..

YieldReaction ConditionsOperation in experiment
With dichloro(1,1'-bis(diphenylphosphanyl)ferrocene)palladium(II)*CH2Cl2; sodium carbonate; In 1,4-dioxane; methanol; at 80℃;Inert atmosphere; A 2 M aqueous Na2CO3 solution (1 .51 mL) is added to a mixture of 5-bromo-1 ,3- difluoro-2-iodo-benzene (1 .00 g) and 5-(4,4,5,5-tetramethyl-[1 ,3,2]dioxaborolan-2-yl)- 2-triisopropylsilanyl-oxazole (1 .87 g) in 1 ,4-dioxane (9 mL) and methanol (3 mL). The mixture is sparged with argon and [1 ,1 '-bis(diphenylphosphino)-ferrocene]dichloro- palladium dichloromethane complex (380 mg) is added. The resulting mixture is stirred at 80C overnight. Since the conversion is not complete, the same amounts of 5-(4,4,5,5-tetramethyl-[1 ,3,2]dioxaborolan-2-yl)-2-triisopropylsilanyl-oxazole, 2 M aqueous Na2CO3 solution, and catalyst are added and the mixture is again stirred overnight at 80C. The triisopropylsilyl protecting group is cleaved under these conditions. After cooling to room temperature, ethyl acetate and water are added. The aqueous phase is extracted with ethyl acetate and the combined organic phases are washed with brine, dried over MgSO4, and concentrated in vacuo. The residue is chromatographed on silica gel (cyclohexane/ethyl acetate 1 :0? 1 :1 ) to afford the title compound. LC (method 4): tR = 1 .18 min; Mass spectrum (ESI+): m/z = 260/262 (Br) [M+H]+.
