Amide metallation reactions: synthesis and X-ray crystal structures of [Ru(NHCOCF3)2(H2O)(CO)(PPh3)2], [Ph3P)(OC)Ru(µ-NHCOC6H4-o)(µ-NHCOPh)(µ-H)Ru(CO)(PPh3)2] and [Ru2(µ-Cl)(µ-H)(µ-NHCOCF3)2(PPh3)4]

Abstract
Amides, NH2COR (R = CF3, Ph), undergo metallation reactions to form mono- and bi-nuclear ruthenium(II) amido complexes, notably [Ru(NHCOCF3)2(H2O)(CO)(PPh3)2], the cyclometallated (N,C) benzamido derivative [Ph3P)(OC)[graphic omitted]6H4-o)(µ-NHCOPh)(µ-H)Ru(CO)(PPh3)2] and the quadruply bridged species [Ru2(µ-Cl)(µ-H)(µ-NHCOCF3)2(PPh3)4] all of which have been characterised by X-ray diffraction methods.
