Abstract
Abstract Photohomolysis of Ti−O bonds is utilized in photocatalytic generation of titanium(III) species for dehydroxylative dimerization of benzylic alcohols under UV‐light irradiation by using isopropyl alcohol (IPA) as a stoichiometric reductant. In this reaction, IPA works not as a single‐electron donor as in the photo‐redox catalyzed reactions but as an H‐atom‐donor. The reaction also proceeds under visible‐light irradiation in the presence of thioglycolic acid as a ligand.
