We show that the carboxylate radical acts as an L-ligand with certain high-spin transition metal centers. Such coordination preserves the O-radical character needed for C–H activation via hydrogen atom transfer. Capture of the new C-radical by the metal and subsequent reductive elimination leads to formal C–H acyloxylation. Decarboxylation of the RCO2 radical is minimized through hybridization effects introduced by spiro-cyclopropyl moiety.
