Abstract: | Heterometallic diyndiyl complexes containing tungsten linked to metals of Groups 6-12 through a C4 bridge are readily prepared from simple derivatisation reactions of the complex W(C ≡ CC ≡ CH)(CO)3Cp bearing the parent diynyl ligand. Complexes {Cp(OC)3W}C ≡ CC ≡ C{ML(n)} [ML(n) = M(CO)(x)Cp (n = 3, M = Mo, W; n = 2, M = Fe, Ru), M(CO)(PPh3)2 (M = Rh, Ir), Au(PPh3)] have been obtained from CuI-catalysed reactions of W(C ≡ CC ≡ CH)(CO)3Cp (1) with MXL(n) (X = halide) in NHEt2. Similarly, cis-PtCl2L2 (L = PEt3; L2 = dppe, dppp) afforded cis-Pt{C ≡ CC ≡ C[W(CO)3Cp]}2L2. Lithiation of 1 (LiNPr2/(i), followed by coupling with MnI(CO)5, gave {Cp(OC)3W}C ≡ CC ≡ C{Mn(CO)5}, while direct reaction of 1 with Hg(OAc)2 gave Hg{C ≡ CC ≡ C[W(CO)3Cp]}2. The Rh and Ir complexes react readily with O2 at the Group 9 metal centre; the crystal structures of {Cp(OC)3W}C ≡ CC ≡ C{Ir(CO)(PPh3)2(O2)} and cis-Pt{C ≡ CC ≡ C[W(CO)3Cp]}2(PEt3)2 are reported.
