  Synthesis of new (cyclopentadienyl)rutheniumphosphine complexes with hemilabile ether-phosphines. The X-ray structure of (η5-C5H5)RuCl(Ph2PCH2CH2OCH3)2

  摘要：

  The reaction of CpRuCl(PPh3)2 (Cp=eta-5-C5H5) with excess ether-phosphine ligand (O,P=Ph2PR, where R is ether containing alkYl chain) in toluene or n-heptane leads to the mixed complexes CpRuCl(PPh3)(P approximately O) and/or the bis(ether-phosphine) complexes CpRuCl(P approximately O)2. A single X-ray structure determination has been carried out for CpRuCl(Ph2PCH2CH2OCH3)2 (4a): space group P1, a=9.2806(6), b=11.9454(8), c=15.2216(9) angstrom, alpha=84.482(9), beta=74.592(5), gamma=85.066(8)-degrees, V=1616.1(3) angstrom3, F(000)=712, D(x)=1.42 g cm-3, Z=2, R=0.064, R(w)=0.075. Treatment of 4a with AgSbF6 affords the salt [CpRu(P O) (P approximately O)][SbF6] (5a), with one mono- (P approximately O) and one bidentate coordinating (P O) ether-phosphine ligand. The fluxional behaviour of the cation of 5a has been studied by temperature dependent P-31{H-1} NMR investigations. Stirring 5a under an atmosphere of carbon monoxide resulted in the formation of [CpRu(P approximately O)2(CO)][SbF6] (6a). All complexes have been characterized by H-1, P-31{H-1}, C-13{H-1} NMR, IR, mass spectroscopy and elemental analysis.
