selective C–H lactonization of fatty acids (C5–C16), catalyzed by manganese(II) complexes bearing bis-amino-bis-pyridine ligands. The catalyst system uses the environmentally benign hydrogen peroxide as oxidant and exhibits high efficiency (100–200 TON), providing under optimized conditions γ-lactones in 60–90% yields. Remarkably, by changing the reaction conditions, the oxidation of hexanoic acid can be
