Frontispiece: Merging Photocatalysis with Chiral Lewis Acid Catalysis for Enantioselective Hydrosilylation/Hydrogermylation of Electron-Deficient Alkenes

The picture depicts a water droplet symbolizing research converging into “chemistry's ocean”. Inside, mountains symbolize reaction energy barriers. Anthraquinone enables silanes/germanes to “climb” these barriers under light, forming radicals that enter the “reaction sea.” As substrates, catalysts and products interact, their dynamic exchange creates rippling waves. A chemist (boatman) continuously casts reactants into the reaction sea. Upon completion, the products are harvested. Details of the study are reported by Xiaoming Feng et al. in their Research Article (e202504676).
