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)2L2in 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 temperature1H and31P{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)4PPh2and 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.
