    Dimethyl acetylenedicarboxylate reacts with [W(CO)3(η-C5H5)}2] under u.v. irradiation to yield the dimetallocycle [W2(CO)4µ-η2,η2-C(O)C2(CO2Me)2}(η-C5H5)2], which ejects CO readily to give [W2(CO)4µ-C2(CO2Me)2}(η-C5H5)2]; in both structure, determined by X-ray diffraction, and reactivity [W2(CO)4µ-η2η2-C(O)C2(CO2Me)2}(η-C5H5)2] is subtly different from the complexes [M2(CO)(µ-CO)µ-η1,η3-C(O)C2R2}(η-C5H5)2](M = Fe or Ru).

    to R 0.033 for 5 045 diffractometer-measured reflection intensities. The molecule contains a ditungsten unit, one atom of which is part of a metallocyclobutenone ring whose ethylenic bond is η2-co-ordinated to the other tungsten. The compound is fluxional, n.m.r. spectra identifying a process (ΔG‡ 77 kJ mol–1) which appears to involve an oscillation of the bridging unit with retention of the alkyne–carbonyl

Further reaction of 1b with PhCHO in aqueous NaOH solution gave an aldol condensation product, [eta(5)-PhCH=CHC(O)C5H4(CO)(2)Mo](2) (mu-C2H2) (4), whereas 3b and 3c reacted with NaBH4 in MeOH to afford corresponding reductive products [eta(5)-MeCH(OH)C5H4(CO)(2)MoW(CO)(2)C(5)H(4)R-eta(5)] (5, R = H; 6, R = CO(2)Me). All these new complexes were fully characterized by combustion analysis, IR, H-1 NMR and mass spectroscopy, and by X-ray crystallography. Copyright (C) 1996 Elsevier Science Ltd
