Abstract
PURPOSE:To obtain a phenol, biphenyl, bibenzyl, aromatic aldehyde and ketone compound under ordinary temperature and pressure by the photochemical reaction of a compound having an aromatic ring in the presence of O2 and water and a specific semiconductor as a catalyst with irradiation of light. CONSTITUTION:A semiconductor having a band gap <=0.5lV as a catalyst is dispersed in water, and a compound having an aromatic ring expressed by formulaIor II (A1-A6 are substituent groups, e.g. OH, and alkyl such as CH3 or C2H5 or vinyl, allyl, phenyl, etc. having an unsaturated bond, OCH3, NO, halogen, etc.; the groups adjacent to A1-A6 are linked to form a polycyclic compound) is added thereto. The resultant mixture is then irradiated with light in the presence of oxygen to carry out the photochemical reaction and give the aimed compound. Titanium, oxide, barium titanate, zinc oxide, silicon oxide, etc. may be used alone as the semiconductor; however, palladium oxide, ruthenium oxide, Pt, Ni, etc. may be present for enhancing the oxidation reduction ability.
