From the Musacchio Lab (Buffalo) and #PfizerChemistry is a new #OLasap with #PhotoChem C-H amination with sulfonamides - great scope. LA addition was key to eliminate competing pathway
Elucidation of a Parasitic Proton-Coupled Electron Transfer in a Photocatalytic Benzylic C–H Sulfonamidation
Strategies for C–H amination with sulfonamides have been dominated by stoichiometric strategies or Rh/Cu catalysis using strong oxidants, elevated temperatures, or excess equivalents of C–H partner. We developed a photocatalytic C–H amination with a bench-stable N-methoxypyridinium salt that is amenable to late-stage functionalization efforts. We discovered a competitive proton-coupled electron transfer pathway between sulfonamide and a pyridine byproduct that inhibits the reaction. Catalysis was re-established with the introduction of ZnBr2.
