N2 - The bis-alkyne complex [M(?5-C5 H5)Cl(CF3 CCCF3)2] (M = W) undergoes metathetical reactions with TlSR (R = Ph, 4-MeC6 H4, Et, i-Pr or t-Bu) to give complexes of stoichiometry [W(?5-C5 H5)SR(CF3 CCCF3)2] which, with the more electron donating groups R, exist as sulphur-bridged dimers. Thallium acetate gives [M(?5-C5 H5)MeC(O)O(CF3 CCCF3)2] (M = Mo, W) with a monodentate acetate ligand while Na S2 CNR2 (R = Et) gives [M(?5-C5 H5)S2 CNR2 (CF3 CCCF3)2] (M = Mo, W) containing a bidentate dithiocarbamate ligand. [W(?5-C5 H5)S-4-MeC6 H4 (CF3 CCCF3)2] gives 1 1 adducts in reactions with uncharged nucleophiles PEt3, PMe2 Ph and P(OMe)3. Acetylene propeller rotation is observed in several of these derivatives. © 1980.
