The invention relates to a composition comprising a soluble source of manganese, a ligand, a base, hydrogen peroxide and a ketone or an aldehyde, wherein the ligand is a pyridine heterocycle containing carboxylic acid or a precursor thereof, wherein the nitrogen atom of the pyridine ring is capable of coordinating to the carboxylate bonded manganese center, wherein the 2-position relative to the nitrogen atom is part of the N(pyridine)-Mn-O(carboxylate) containing chelate ring and the second 2-position relative to the nitrogen atom in the ring is not a carboxylic acid group. Furthermore, the invention relates to a process for oxidation of an organic substrate using the composition of the invention.
