Abstract
Despite the high reactivity of alkoxyl (RO·) radicals and their propensity to easily undergo β-scission or Hydrogen Atom Transfer (HAT) reactions, an efficient photoredox-mediated intermolecular trapping of alkoxyl radicals by silyl enol ethers enables the introduction of both structurally simple and more complex alkoxy groups into a wide range of ketones and amides.
