4'-BROMO-4-BIPHENYLBORONIC ACID Use and Manufacturing
Sub 1-2-1 (4) (9.4g, 30mmol) dissolved in anhydrous Ether, a reaction temperature of-78 ° C to a lower, n-BuLi (2.5M in hexane) (2.1g, 33mmol) was slowly addeddropwise and after I, the reaction is stirred for 30 min. After the dropwise additionTriisopropyl borate (8.5g, 45mmol) lowering the temperature of the reaction back to -78 ° C. Stirring at room temperature, diluted with water and it binds the 2N HCl. Aftercompletion of reaction, ethyl acetate and water, dried over MgSO4 and the organic layerwas extracted and concentrated and to the resulting organic silicagel column andrecrystallized to obtain 5.9g of Sub 1-2-2 (4). (Yield: 71percent)10.0 g (0.032 mol) of 4, 4'-dibromobiphenyl was put in a 500 mL three neck flask, and nitrogen was substituted for air in the flask, and then 200 mL of tetrahydrofuran was added and stirred at -80
