Norbert Hoffmann studied chemistry at the RWTH Aachen University, Germany, and received his Ph.D. degree in 1992 under the supervision of Hans-Dieter Scharf. In 1993, he secured a permanent research position at the CNRS (Chargé de Recherche) in Reims, France. In 2004, he was appointed Research Director in the CNRS. His research interests are in the field of organic photochemistry: electron transfer, photoinduced radical reactions, cycloadditions of aromatic compounds, and application of these reactions to organic synthesis. His other research activities involve the production of fine chemicals from biomass and the synthesis of new organic semiconductor materials for microelectronics.

Abstract

Titanium dioxide is a versatile heterogeneous catalyst. Absorption of light by a TiO2 particle leads to the formation of an electron–hole pair. Electron transfer from or to the particle induces redox reactions. Although mainly applied in the context of environmental chemistry, these processes are also used to selectively transform organic compounds. Oxidations and reductions have been carried out. Applications to the synthesis of heterocycles have been reported. Many C–C bond formation reactions have been performed. Owing to adsorption of the substrates or by different surface modifications, visible light can be used to excite the catalytic system, which generates mild reaction conditions.
