Product Name:4-Phenylphenol
CAS Number:92-69-3
Molecular formula:C12H10O
Molecular Weight:170.21

4-phenylphenol synthesis: Add to a 50 ml round-bottom flask, in this order, 122 mg of phenylboronic acid, 414 mg of potassium carbonate, 220 mg of 4-iodophenol, and 10 ml of deionized water. Weigh in a suitably sized container 3 mg Pd on C 10%, add 1 ml of deionized water, and stir gently by hand to form a slurry that is then transferred to the reaction flask.
synthesis of 4-phenylphenol

Couple the flask to a water-jacketed condenser, and reflux the mixture on a hot plate with a magnetic stirrer vigorously for 30 min (until a precipitate appears). After this time, switch off the plate and allow to cool to r.t. Add HCl 2 M to an acidic pH (check with indicator paper). Separate the resulting solid, still containing the catalyst, by filtering with a Hirsch funnel. Wash the solid with 10 ml of water. Then, in a Hirsch funnel, add 10 ml of MeOH, and collect the filtrate in a clean container. Add to the resulting MeOH solution 10 ml of deionized water to obtain the precipitate of the product. Purify by recrystallization, heating in a water bath container with the precipitate and the MeOH/H2O mixture. If necessary, add 1 to 2 ml more of hot MeOH, to finish dissolving the solid. Filter under vacuum with a Hirsch funnel, air dry the solid (can recover the next day). Weigh and calculate the yield.

Reaction Conditions:

with water;ethylene glycol;potassium hydroxide;copper dichloride in dimethyl sulfoxide at 120; for 24 h;Inert atmosphere;Reagent/catalyst;Temperature;

Steps:

General Procedure A.

To a test tube containing a magnetic bar was added aryl halide (1.0 mmol), CuCl₂ (13.4 mg, 0.1 mmol), KOH (336 mg, 6.0 mmol), ethylene glycol(12 μL, 0.2 mmol), and DMSO/H₂O (1.0 mL/0.5 mL). After flushing with argon, the mixture was stirred in a preheated oil bath at 120 °C for 24 h. After cooled to ambient temperature, the reaction mixture was distributed in aqueous HCl (5 %) and ethyl acetate. The organic layer was washed with water and brine, dried over anhydrous MgSO₄, and concentrated under vacuum. The crude product was further purified by column chromatography (EtOAc/n-Hexane) to provide the phenols.
