The development of general anti-Markovnikov hydroalkoxylation methods remains challenging due to competing alkene oxidation and photocatalyst–alcohol compatibility issues. Herein, diaryl diselenides serve as efficient electron-shuttle catalysts for visible-light-driven anti-Markovnikov hydroalkoxylation in combination with TPT+BF4–. A broad range of aryl- and alkyl-substituted alkenes and diverse alcohols are accommodated, affording products up to 97% yield. Mechanistic studies reveal a diselenide-mediated, multistep electron-shuttle pathway that enables mild and selective transformations.
