A Multiphoton Single-Electron Reduction of Olefins via Tandem Photoredox Catalysis
Preprints are manuscripts made publicly available before they have been submitted for formal peer review and publication. They might contain new research findings or data. Preprints can be a draft or final version of an author's research but must not have been accepted for publication at the time of submission.
Herein we report a visible light multiphoton tandem photoredox catalysis strategy enabling a distinctive mode of olefin activation via a one electron reduction to the corresponding radical anion. This highly nucleophilic intermediate was harnessed to develop a method for the formal hydrogenation of unactivated alkenes under mild reaction conditions, in the absence of hydrogen gas or dissolving metals.
