  摘要：

  Ligand substitution in W(CO)(4)(NO)(ClAlCl3) with 2-(dimethylphosphino)imidazole (dmpi) bearing an acidic NH functionality afforded W(Cl)(CO)(NO)(bdmpi)(dmpi) (1) (bdmpi = 1,2-bis(dimethyl-phosphino)imidazole), while the reaction of dmpi with W(Cl)(NO)(P(OMe)(3))(4) led to the isolation of W(Cl)(NO)(dMPi)(4) (2) together with W(Cl)(NO)(bdmpi)(dMPi)(2) (3). Attempts to replace the chloride by a hydride ligand in 1-3 applying various hydride reagents did not lead to stable products. The soluble compound W(Cl)(NO)(dmpe)(dmpi)(2) (5) was prepared by an alternative route from W(Cl)(NO)[P(OMe)(3)](4) via the intermediacy of W(Cl)(NO)(P(OMe)(3))(2)(dmpe) (4). The protection of the NH function in 5 was approached applying BuLi and subsequently Me3SiCl to afford [W(Cl)(NO)(dmpe)(tmsdMPi)(2)] (tmsdmpi = 1-trimethylsilyl-2-dimethylphosphino-imidazole) (6) which could not be isolated in pure form. The reaction of 5 with NaHBEt3 led to the formation of a deprotonated and nitrogen-coordinated salt Na[W(NO)(dmpe)(dmpi)(tebdmpi)] (7) (tebdmpi = 2-dimethylphosphino-3-triethylboro-imidazole). Compound 7 crystallized from CH3CN to establish a one-dimensional chain structure in the solid state. The structures of compounds 1-5 and 7 were studied by single-crystal X-ray diffraction.
