  Alkynylcarbyne complexes containing various tri- and bidentate ligands such as cyclopentadienide, tris(pyrazolyl)borate, bis(pyrazolyl)acetate and tmeda: synthesis and spectroscopic properties

  摘要：

  The (alkynylcarbyne) tungsten complexes [L-3(CO)(2)WdropC-CdropC-R] (3a,b-6a,b) [L-3 = hydro[tris(3,5-dimethylpyrazol-1-yl)]borato (Tp', 3), hydro[tris(pyrazol-1-yl)]borato (Tp, 4), cyclopentadienyl (Cp, 5), bis(3,5-dimethylpyrazol-1-yl)acetato (bdmpza, 6); R = SiMe3 (a), Ph (b)] were prepared in a stepwise fashion from [W(CO)(6)] and Li[CdropCR], (CF3CO)(2)O and M[L-3] (M = Na, K). The formation of 6a,b was highly selective, only complexes with a trans arrangement of the carboxylate group of bdmpza and the alkynylcarbyne ligand were detected. The reaction of [W(CO)(6)] with Li[CdropCR], C2O2Cl2 and tmeda afforded trans[Cl(CO)(2)(tmeda)WdropC-CdropC-R] (7a,b). The electron-donating potential of the different tripodal ligands L-3 was studied by IR- and C-13-NMR spectroscopy and compared to that of the ligand combination Cl/tmeda. The IR data suggest that in these complexes bdmpza is a weaker electron donor than Tp' and Tp but displays stronger electron-donating abilities than Cp. The structures of 6b and 7b were established by X-ray structural analyses. (C) 2002 Elsevier Science B.V. All rights reserved.

The identities of 1-3 have been confirmed by single-crystal X-ray diffraction studies. Cluster 1 contains mu(4)-carbido and mu-oxido ligands resulting from CO cleavage. Cluster 2, with sterically more encumbering tetramethylcyclopentadienyl ligands that arrest CO cleavage, possesses a mu(3)-eta(2)-CO ligand with a weak CO bond (1.272(7), 1.257(7) angstrom). Cluster 2 could not be converted into an analogue of cluster 1. The reaction with alkyne is more facile than the reaction with alkylidyne; cluster 3 results from addition of the C C bond (rather than the W C bond) across the Mo-Mo vector.
