Yield:2713-33-9 92%

Reaction Conditions:

with dihydrogen peroxide in water at 20; for 0.0833333 h;

Steps:

General procedure for ipso-hydroxylation of arylboronic acids
General procedure: A mixture of arylboronic acid (0.5 mmol), 10 mg cellulose (15 wt%) and 2 mL distilled H2O were taken in an oven dried 10 mL round bottomed flask. To this 30% aq H2O2 (0.5 mL) was added dropwise and stirred at room temperature for 5 min. After completion of the reaction (monitored by TLC), aqueous layer was centrifuged to recover the catalyst for further use. The products were extracted with EtOAc (3x10 mL), dried with anhydrous Na2SO4 and then vacuum dried. The crude product was purified by column chromatography on silica gel (EtOAc/ hexane) to obtain the desired product.
