The latest issue of Photochemical & Photobiological Sciences is now available online. This issue is dedicated to Jean-Pierre Desvergne in honour of his lasting contributions to the field of photochemistry. Read the Editorial here.
The front cover of this issue highlights a recent Perspective article by Norbert Hoffmann from CNRS and the University of Reims Champagne-Ardenne, France, on “Photochemical reactions of aromatic compounds and the concept of the photon as a traceless reagent.” In this perspective, Hoffmann focuses on the photochemical transformations of aromatic compounds (mainly benzene derivatives) and their applications to organic synthesis. The various transformations looked at do not require chemical activation and instead use photons as the reagent. Examples include photocycloaddition reactions, including [2 + 3] meta photocycloaddition, and photochemical electron transfer induced reactions which have been intensely studied in recent years. Hoffman shows that mainly of these procedures can be applied to the synthesis of complex compounds, and although they are not yet used in industry, the ecological and economical potential of these processes is demonstrated.
