AbstractThe complex [(η6-p-cymene)OsCl(CHPh)(IPr)]OTf (1) reacts with 2,6-diacetylpyridine in acetonitrile at 40 °C to give the [C,N,O]-pincer derivative [OsCl{κ3C,N,O-[CHC(O)pyC(CH3)O]}(NCCH3)(IPr)]OTf (2), containing an alkylidene function at the terdentate ligand. Under the same conditions in dichloromethane, the neutral species OsCl(OTf){κ3C,N,O-[CHC(O)pyC(CH3)O]}(IPr) (3) is formed.
