  Alkynylcarbyne(bipyridine)dicarbonyl(triflouroacetato) complexes—synthesis and detection of reversible association in solution

  摘要：

  A series of alkynylcarbyne(bipyridine)(dicarbonyl)trifluoroacetato complexes, [CF3COO(L-L)(CO)(2)MdropC-CdropC-R] (M = W, Mo; L-L = 2,2'-bipyridine, 4,4'-dimethyl 2,2'-bipyridine; R = SiMe3, Ph, p-Tol, t-Bu), has been prepared by sequential reaction of [M(CO)(6)] with Li[CdropCR], trifluoroacetic anhydride, and L-L. All complexes were fully characterized. Concentrated solutions of these complexes exhibit two sets of v(CO) absorptions (instead of the expected one set (A(1)/B-1). The ratio A(1)/B-1:A(1)(*)/B-1(*) is concentration-dependent and decreases with increasing concentration of the complexes in solution. This phenomenon is discussed on the basis of a reversible association of complex molecules to form dimers and oligomers prior to precipitation and crystallization. (C) 2002 Elsevier Science B.V.
