Research Abstract

Photocatalytic oxygenation of benzene occurs in an oxygen-saturated acetonitrile solution containing 2,3-dichloro-5,6-dicyano-pbenzoquinone(DDQ), benzene and waterunder UV light irradiation to yield phenol. In the presence of tert-butyl nitrite, phenol was formed photocatalytically via recovery from 2,3-dichloro-5,6-dicyanohydroquinone to DDQ. The conversion of benzene as a reactant was 61% and selectivity of phenol formation was 92%under the catalytic conditions.
