A slow electron waltz: Catalysis in single-electron steps with radicals as intermediates is essential for an atom-economical arylation of epoxides with a proton-coupled electron transfer as a key step. Stabilization of the catalyst is essential for low catalyst loading, as demonstrated by reaction-progress kinetic analysis, cyclic voltammetry, and calculations.
