Combining simple iron and thiol catalysts allows carboxylic acids to be directly converted to C−H bonds under visible light irradiation. The cocatalytic system exhibits a wide scope, is scalable, and preliminary mechanistic studies suggest it functions via a tandem ligand-to-metal charge transfer (LMCT)/Hydrogen Atom Transfer (HAT) mechanism.
