Description
Dae Young Bae and colleagues report in 2026 palladium complexes that break carbon-hydrogen bonds using plain oxygen in water. Chemists often need harsh oxidants and added bases for such steps, which limits green use. Their palladium sat inside a four-armed ring ligand that holds the metal while leaving a working site open.
Left in air with mild heating, the complex took up oxygen and cut a carbon-hydrogen bond without any added base. Oxygen served two roles, driving the oxidation and soaking up the released proton. The product was a stable higher-valence palladium species formed in full yield under the best conditions. Computer and lab evidence point to a joint metalation and proton removal step as the slow point.
