Embodiment 1
[0137] Example 1 Preparation of 3-allyl-[1,1'-biphenyl]-4-phenol
[0138]
[0139] Step 1: Preparation of 1-allyloxy-4-bromobenzene
[0140] 4-Bromophenol (3.46g, 20mmol) and potassium carbonate (3.6g, 26mmol, 1.3equiv.) were added to 25ml of acetone solvent and stirred, then allyl bromide (1.9ml, 22mmol, 1.1equiv.) Slowly added dropwise to the reactor. The temperature was raised to a reflux state and the stirring was continued. After 5 hours of reaction, the reaction was terminated. After cooling down, filter out the solid potassium carbonate, evaporate the acetone from the reaction solution, extract the remaining solution three times with ether, each time 20 ml, wash the combined ether solution once with 20 ml of 10% sodium hydroxide solution, and wash with saturated saline Once, dried over anhydrous magnesium sulfate, and finally concentrated to obtain a colorless oily product (4.05g, 19.01mol, 95.03%).
