  摘要：

  Reaction of WO2Cl2 with K{HB(Me2pz)3} [HB-(Me2pz)3- = hydrotris(3,5-dimethyl-1-pyrazolyl)borate anion] in N,N-dimethylformamlde produces cis-{HB-(Me2pz)3}WO2Cl (1), which reacts with Grignard reagents in tetrahydrofuran to yield the organometallic dioxo-W(VI) complexes cis-{HB(Me2pz)3}WO2(R) (R = Me (2), Et (3), CH2Ph (4), Ph (5)). The X-ray structures of 3 and 5 reveal that the monomeric complexes possess distorted-octahedral coordination spheres composed of a facially tridentate HB(Me2pz)3- ligand, two terminal oxo ligands, and an eta-1-hydrocarbyl group.

  Reactions of cis-[HB(Me2pz)3}WO2Cl] with Grignard reagents RMgX (R = Me, Et, CH2Ph, Ph; X = Cl or Br) in tetrahydrofuran, or boron sulfide in refluxing 1,2-dichloroethane, result in the formation of organometallic dioxo-WVI complexes, cis-[HB(Me2pz)3}WO2R], and oxo-thio- and dithio-WVI complexes, cis-[HB(Me2pz)3}WE2Cl](E2= OS, S2), respectively; the X-ray crystal structure of cis-[HB(Me2pz)3}WO2Et], a rare example of a complex stable towards β-hydrogen elimination, is reported.

  The compounds Tp'W(CHR)(E)X (Tp' = hydridotris(3,5-dimethylpyrazolyl)borate; R = CMe3, Ph; E = O, NPh; X = Cl, Br), 4a-c, have been synthesized by reaction of Tp'W(CR)X2 (R = CMe3, X = Cl; R = Ph, X = Br), 3a,b, with neutral alumina or aniline. Compounds 3a,b and 4a - c are air stable and thermally stable to > 100-degrees-C in the solid state. When combined with 1 equivalent of AlCl3, Tp'W(CHPh)(NPh)Br, 4c, catalyzes the acyclic diene metathesis (ADMET) oligomerization of 1,9-decadiene, giving a mixture of 1,9,17-octadecatriene, 1,9,17,25-hexadodecatetraene and ethylene (almost-equal-to 30% conversion). The new alkylidene complex, 4a, is an efficient ring-opening metathesis polymerization (ROMP) catalyst in the presence of AlCl3 as a co-catalyst.
