Photocatalytic alkoxy radical-mediated transformations

Alkoxy radicals have been intensively studied as versatile synthetic intermediates with well-established reactivity and selectivity. Due to the difficulties associated with the generation of these transient and high-energy radicals, the utilization of the unique reactivity of alkoxy radicals in catalytic platforms has become a rather challenging task. Recent studies on the alkoxy radical-mediated transformations have benefited tremendously from advances in modern photoredox catalysis. In this digest, we aim to highlight reported transformations that utilize alkoxy radicals in a photocatalytic fashion, in particular, underline novel catalytic platforms which we anticipate will find broad application in the near future.
