Abstract

Interaction of Ru(OAc)₂(Ph₃P)₂, 1, with one and two equivalents of L (L = Ph₂P(CH₂)_nPPh₂; n = 1-3) in refluxing toluene gave Ru(OAc)₂(Ph₃P)L and Ru(OAc)₂L₂ in good yield, respectively. The solution dynamic of Ru(OAc)₂(Ph₃P)L complexes (L = Ph₂P(CH₂)_nPPh₂; n = 1 and 2) were studied by variable temperature ¹H and ³¹P{¹H} NMR spectroscopy. At -50°C, the two acetate groups exist as a η²- and a η¹-acetate group which exchange rapidly at room temperature. X-Ray diffraction study of Ru(OAc)₂(Ph₃P)(dppm) reveals the presence of a η¹- and a η²-acetate ligand and a fac-configuration for the phosphine ligands. Interaction of 1 with one equivalent of L′ (L′ = Ph₂P(CH₂)₄PPh₂ and P₂N₂H₄) in refluxing toluene gives the corresponding Ru(OAc)₂L′ complex in high yield. X-Ray diffraction study of Ru(OAc)₂(P₂N₂H₄) reviews that the two acetate groups are monodentate coordinated and are in a mutually trans position.
