  名称：

  Reactions of [RuCl₂(PPh₃)₄] with mixed anhydrides of diphenylphosphinous and acrylic acids; structure of [RuCl{(Ph₂PO)₂H}(PPh₃)(O₂CCH₂CH₂PPh₃)]·C₄H₈O

  摘要：

  Reactions of [RuCl2(PPh3)4] with 1 mol equivalent of Ph2PO2CCH = CR'R" produce [RuCl2(PPh3)2(Ph2PO2CCH = CR'R")] (R', R" = H or Me), although for R' = H, R" = H or Me the major product is [RuCl{(Ph2PO)2H}(PPh3)(O2CCH2CHR"PPh3)], which for R" = H has been crystallographically characterized. Using 2 mol equivalents of Ph2PO2CCR = CR'R" the products are [RuCl2(Ph2PO2CCR = CR'R")2] (R = H, R' = R" = Me; R = Me, R' = H, R" = Ph) or [RuCl2(PPh3)(Ph2PO2CCH = CH2)(Ph2POPPh2)]. The complexes have all been characterized spectroscopically and the mixed anhydride ligands are generally co-ordinated through P and O, apparently for steric reasons. Binding through P and the C = C appears to occur in [RuCl2(PPh3)2(Ph2POCH2CH = CMe2)], prepared from [RuCl2(PPh3)4] and Ph2POCH2CH = CMe2, whilst unidentate binding via the P atom is observed for the mixed anhydride in [RuCl2(PPh3)(Ph2PO2CCH = CH2)(Ph2POPPh2)]. Crystal data for [RuCl{(Ph2PO)2H}(PPh3)(O2CCH2CH2PPh3)]: orthorhombic, space group P2(1)2(1)2(1), with a = 15.16(3), b = 23.05(3), c = 17.08(4) angstrom and Z = 4. The structure was obtained from 6558 reflections measured on an automatic diffractometer and refined to an R value of 0.076. The main features of the structure include the zwitterionic triphenylphosphoniopropionate betaine ligand binding via the carboxylate in a chelating fashion and the planar RuPOHPO ring of the bis(diphenylphosphinito)hydrogenate ligand. The O ... O distance in this ligand is 2.382(12) angstrom indicative of strong hydrogen bonding.
