  Synthesis, Characterization, and Acidity Properties of [MCl(H₂)(L)(PMP)]BF₄ (M = Ru, L = PPh₃, CO; M = Os, L = PPh₃; PMP = 2,6-(Ph₂PCH₂)₂C₅H₃N)

  摘要：

  Treatment of RuCl2(PPh3)(3) with PMP (PMP = 2,6-(Ph2PCH2)(2)C5H3N) in acetone produced RuCl2(PPh3)(PMP), which has been characterized by X-ray diffraction. Treatment of RuCl2-(PPh3)(PMP) with NaBH4 in methanol gave RuHCl(PPh3)(PMP), acidification of which with HBF4 . Et2O produced the molecular dihydrogen complex [RuCl(H-2)(PPh3)(PMP)]BF4. Treatment of RuHCl(CO)(PPh3)(3) with PMP in benzene produced RuHCl(CO)(PMP), which reacted with HBF4 . Et2O to give the molecular dihydrogen complex [RuCl(H-2)(CO)(PMP)]BF4. The osmium molecular dihydrogen complex [OsCl(H-2)(PPh3)(PMP)]BF4 was prepared by protonation of OsHCl(PPh3)(PMP) with HBF4 . Et2O. Relative acidities of the dihydrogen complexes were investigated by NMR spectroscopy of equilibrium reactions conducted in CD2Cl2. [RuCl(H-2)(CO)(PMP)]BF4 is more acidic than [RuCl(H-2)(PPh3)(PMP)]BF4, which is in turn more acidic than its osmium analog [OsCl(H-2)(PPh3)(PMP)]BF4.
