Yield:349-58-6 96%

Reaction Conditions:

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

Steps:

General Procedure A.
General procedure: 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.
