Abstract
With an inexpensive and commercially available WO 3 semiconductor as the heterogeneous photocatalyst, a catalytic amount of NPh 3 as the single-electron donor, and ambient air as the single-electron acceptor and oxygen source, the semiheterogeneous photocatalytic hydroxylation of alkyl and aryl boronic acids was developed. A broad range of hydroxylated compounds can be obtained in excellent yields.
