H,D pick and mix : The pyridylidene compounds [Tp Me 2Ir(C 6 H 5 ) (CN(H) C 4 (R)H 3 )] (R=H, Me, and Ph) react with O 2 to form mixtures of two complexes (see scheme). One of them, 4 , contains a newly formed CN bond as the result of an oxidative dehydrogenation. During a mechanistic study on its formation, an unexpected H,D scrambling has been disclosed.
