Front Cover: Photoinduced Enantioselective Triplet Radical Reaction on Metal: Copper-Catalyzed Conjugate Addition of Acylsilanes to α,β-Unsaturated Ketones and Aldehydes (Chem. Eur. J. 65/2024)
A photoinduced copper-catalyzed enantioselective conjugate addition of acylsilanes to α,β-unsaturated ketones and aldehydes has been developed. Metal-to-ligand charge-transfer excitation of an alkene-bound acylcopper intermediate generates a triplet β-radical-C-enolate-CuII-acyl complex with an acyl radical character, which undergoes facile C−C bond formation in the copper coordination sphere. The picture represents the triplet excited state C−C bond formation as a powerful synthetic strategy. More information can be found in the Research Article by M. Gao, M. Sawamura and co-workers (DOI: 10.1002/chem.202402564).
期刊介绍:
Chemistry—A European Journal is a truly international journal with top quality contributions (2018 ISI Impact Factor: 5.16). It publishes a wide range of outstanding Reviews, Minireviews, Concepts, Full Papers, and Communications from all areas of chemistry and related fields.
Based in Europe Chemistry—A European Journal provides an excellent platform for increasing the visibility of European chemistry as well as for featuring the best research from authors from around the world.
All manuscripts are peer-reviewed, and electronic processing ensures accurate reproduction of text and data, plus short publication times.
The Concepts section provides nonspecialist readers with a useful conceptual guide to unfamiliar areas and experts with new angles on familiar problems.
Chemistry—A European Journal is published on behalf of ChemPubSoc Europe, a group of 16 national chemical societies from within Europe, and supported by the Asian Chemical Editorial Societies. The ChemPubSoc Europe family comprises: Angewandte Chemie, Chemistry—A European Journal, European Journal of Organic Chemistry, European Journal of Inorganic Chemistry, ChemPhysChem, ChemBioChem, ChemMedChem, ChemCatChem, ChemSusChem, ChemPlusChem, ChemElectroChem, and ChemistryOpen.
