The front cover illustrates the dual role of the “Magic Blue” molecule. Set in an enchanting forest, a whimsical wizard conjures two gold complexes in a magical cauldron full of “Magic Blue”. The compounds react via chloride abstraction for the [AuCl(JohnPhos)] catalyst and one-electron oxidation for the ferrocenyl imine-phosphane catalyst. Fairies are depicted pulling a chloride atom and an electron, respectively, showcasing the dynamic nature that “Magic Blue” oxidant can adopt depending on the molecule it reacts with. Details can be found in Research Article by Pérez-Sánchez, Herrera, and Gimeno (J. C. Pérez-Sánchez, R. P. Herrera, M. C. Gimeno, Adv. Synth. Catal. 2024, 366, 3697-3924; DOI: 10.1002/adsc.202400593)

The front cover picture was generated by artificial intelligence around our description of the landscape we intended to create. The cascade waterfall symbolizes the cascade transformation depicted schematically on the image. The starting oxime containing a proximal allene in palladium catalyzed process undergoes several in situ transformations to afford the triquinane type product. The cascade stream involves three components and creates four new bonds in a single operation. More details can be found in article by P. Jovanovic, V. Savic and co-workers (P. Jovanovic, M. Jovanovic, M. Petkovic, M. Simic, G. Tasic, M. Rodic, S. Rakic, F. Vlahovic, V. Savic, Adv. Synth. Catal. 2024, 366, DOI: 10.1002/adsc.202400253)

The front cover picture shows two of the founders of fluorine chemistry, Carl Wilhelm Scheele and Henri Moissan, and examples of the fluorine-containing compounds reported in the articles that appear in this special issue of Advanced Synthesis & Catalysis. More information about this issue can be found in the Commentary by the Issue Editor, Véronique Gouverneur (V. Gouverneur, Adv. Synth. Catal. 2024, 366, 3404-3404; DOI: 10.1002/adsc.202400881)

The front cover picture illustrates the synthesis of quinolines based on the strategy of isomerization of allylic alcohols catalyzed by the complex of 1,10-phenanthroline and ^tBuONa. The honeycomb symbolizes the catalyst and development of bees metaphorize the domino isomerization/oxidant-free dehydrogenative annulation sequences. The flying bees stand for the application of this protocol for the synthesis of bioactive molecules. Details can be found in the research article by Jia-Qi Li and co-workers (X. Zhou, X. Li, C. Le, J.-Q. Li, Adv. Synth. Catal. 2024, 366, 3316-3322; DOI: 10.1002/adsc.202400465)
