ZWITTERION-RUTHENIUM COMPLEX FOR CATALYTIC AEROBIC OXIDATION REACTIONS
Zwitterion ligand metal complexes and methods of aerobic oxidation using a zwitterion ligand metal complex are provided. The zwitterion ligand metal complexes can include a transition metal salt and a zwitterion ligand, which can comprise a non-conjugated amide anion-phosphonium cation, an amide anion-ammonium cation, or an iminium cation. The methods of aerobic oxidation can include combining the zwitterion ligand metal complex with an oxidizable compound and molecular oxygen to allow the isolation of an oxidized compound from the oxidizable compound.
