The combination of N-heterocyclic carbene (NHC) organocatalysis with photochemical activation is becoming increasingly established as an approach for conducting radical organic reactions under mild and practical conditions. As comparatively easy to prepare handle compounds, alkyl silanes are attractive substrates chemistry desilylative mesolysis the corresponding cations known be rapid. Here, we report successful application benzyl silane derivatives source radicals in dual NHC/photoredox-catalyzed radical–radical coupling acyl fluorides. Relatively electron-rich reacted smoothly afford ketones generally good yields, while optimization NHC photocatalyst allowed a wider scope including primary substrates. Furthermore, initial experiments revealed that organosilanes bearing N-, O- S-heteroatoms can also serve sources these
