Reaction Conditions:

with oxygen;triethylamine in acetonitrile; under 760.051 Torr; for 4 h;Irradiation;

Steps:

2.3. Photocatalytic hydroxylation of phenylboronic acid

General procedure: The photocatalytic hydroxylation of phenylboronic acid wascarried out as following: Catalyst (10 mg) and phenylboronicacid (0.5 mmol) was poured into the mixture solution with triethylamine (TEA, 1.5 mmol) dissolved in the acetonitrile (3 mL).Then, the mixture was transferred into a 10 mL Pyrex glass bottlefilled with pure oxygen at atmospheric pressure. The suspensionswere irradiated by a blue LED lamp. After the reaction, the mixturewas centrifuged to completely remove the catalyst particles. Thefiltered solution was analyzed by 1H NMR spectrum using 1, 3, 5-Trimethoxybenzene as the internal standard.
