    Mixed alkoxide-anilide d3-d3 dimers of molybdenum and tungsten. The X-ray crystal structures of M2(OBut)4(HNPh)2(H2NPh)2 (M = Mo, W)
    摘要:
    The reactions in diethyl-ether/hexane solutions between aniline and M2(OBut)6 (M = Mo, W) produce M2(OBut)4(HNPh)2(H2NPh)2 in high yield (79-85%) as red-black crystals. The compounds are air-sensitive, soluble in aromatic hydrocarbon solvents, and exhibit dynamic NMR behaviour. The IR spectra show nu(N-H) at 3320 and 3100 cm-1, corresponding to aniline and anilide N-H stretches, respectively. The X-ray crystal structures of M2(OBut)4(HNPh)2(H2NPh)2 are isomorphous for molybdenum and tungsten and reveal eclipsed four-coordinate, essentially planar ends supporting a metal-metal triple bond. Some important bond lengths and angles for W2(OBut)4(HNPh)2(H2NPh)2 (Mo2(OBut)4(NHPh)2(NH2Ph)2 in parentheses) are as follows (at - 169-degrees-C and - 168-degrees-C): M-M 2.3225(8) [2.2538(7)], M-O = 1.93 (1.94) (ave), 1.98 (1.96) (ave), M-N (amide) 1.97 (ave) [1.99 (ave)], M-N (amine) 2.37 angstrom (ave) [2.36 angstrom (ave)].

  • α-Hydrogen migration reactions in tungsten(VI) cyclopentadienyl alkylidyne complexes

    CpW(CAd)(CH2CMe3)Cl and CpW(CAd)(CH2CMe3)2 tautomerize to give mixtures containing CpW(CCMe3)(CH2Ad)Cl and CpW(CCMe3)(CH2CMe3)(CH2Ad), respectively. An X-ray study of CpW(CAd)(CH2CMe3)2 is consistent with some α agostic interaction of a neopentyl proton in each neopentyl ligand with the metal. In contrast, CpW(CAd)(NMe2)(CH2CMe3) shows no evidence of tautomerizing to CpW(CCMe3)(NMe2)(CH2Ad) at room temperature over

    complex [W(CO)2(η2-PCAr‘)W(CO)5}2] (7) is formed. The function of [W2(OtBu)6] in this reaction is uncertain, but stoichiometric amounts of [W2(OtBu)6] are essential to obtain complex 6. Reduction of the size of the alkoxide ligands by the use of [W2(ONp)6] (Np = CH2tBu) in the three-component reaction with Ar‘C⋮P leads to the trinuclear cluster compounds [W3〈(μ3-P)W(CO)5}〉(μ-ONp)3(ONp)6] (8) and [W
