Stabilized with an N‐heterocyclic carbene ligand of the smallest steric profile, Pd II (η 2 ‐O 2 )( I Me) 2 ( I Me = 1,3‐dimethylimidazole‐2‐ylidene) was synthesized by the direct addition of dioxygen to Pd 0 ( I Me) 2 . The peroxidopalladium complex with I Me, which was previously available only by computation, was characterized by IR spectroscopy and X‐ray crystallography. Moreover, its oxygen‐atom‐transfer reactivity was elucidated by studying its thermolysis in pyridine at 60 °C to yield 1,3‐dimethylimidazol‐2‐one ( I MeO) and its reaction with oxygen‐atom‐transfer acceptors such as PPh 3 and (Me 3 Si) 2 .
