  Mechanistic information of substitution reaction of W(PhC≡CPh)3(CO) with trimethylphosphine

  摘要：

  Substitution reaction of W(PhC=CPh)(3)(CO) (1) with PMe3 to give W(PhC=CPh)(3)(PMe3) (2) has been studied by IR and NMR spectroscopy as well as cross-over experiments. A metastable intermediate W(CO)(PhC=CPh)(2)(PMe3)(2) (3) is produced by adding two PMe, moieties into 1 accompanied with loss of a PhC=CPh ligand. Subsequent conversion from 3 to 2 might involve decarbonylation and PMe3/PhC=CPh exchange. (C) 1997 Elsevier Science S.A.

  摘要：

  Reactions of W(PhC=CPh)(3)L (L=CO or NCMe) with PMe3, PPh2Me and PPh3 produce W(PhC=CPh)(3)(PMe3), W(PhC=CPh)3(PPh2Me) and W(PhC=CPh)(3)(PPh3), respectively. Reaction of W(PhC=CPh)(3)(NCMe) with 1,1'-bis(diphenylphosphino) ferrocene (dppf) forms W(PhC=CPh)(3)(eta(1)-dppf) and [W(PhC=CPh)(3)](2)(eta(1),eta(1)-dppf). Treating W(RC=CR)(2)(eta(4)-C4R4) (NCMe) (R=Ph and Tol) with PMe3 affords W(RC=CR)(2)(eta(4)-C4R4)(PMe3). W(PhC=CPh)(3)(PMe3) crystallizes in the space group P (3) over bar with a=14.000(4), c=11.183(3) Angstrom, V=1898.3(7) Angstrom(3), Z=2 and R-F=0.032. W(TolC=CTol)(2)(eta(4)-C(4)Tol(4))(PMe3) crystallizes in the space group P2(1)/c with a=13.588(2), b=19.289(5), c=22.150(5) Angstrom, beta=90.57(2)degrees, V=5805.(2) Angstrom(3), Z=4 and R-F= 0.055.
