Abstract

The bis(cyclopentadienyl)metal dihalides [MCl₂(η-C₅H₅)₂] (M = Ti or Zr) are reduced by magnesium amalgam in tetrahydrofuran in the presence of the alkylidyne-tungsten complexes [W(≡CR)(CO)₂(η-C₅H₅)] (R = C₆H₄Me-4 or C₆H₄OMe-2) to afford the dimetal compounds [MW(μ-CR)(μ-σ:η²-CO)(CO)(η-C₅H ₅)₃]. Alternatively, the reagents [M(Buⁿ)₂(η-C₅H₅)₂] (M = Ti or Zr), prepared in situ in diethyl ether, react with the complexes [M′(≡CR)(CO)₂(η-C₅H₅)] (M = Ti, M′ = W, R = C₆H₄Me-4 or C₆H₄OMe-2; M = Zr, M′ = W, R = Me, C₆H₄Me-4,C₆H₄OMe-2, or C₆H₃Me₂-2,6; M′ = Mo, R = C₆H₄OMe-2) to give the compounds [MM′(μ-CR)(μ-σ:η²-CO)(CO)(η-C ₅H₅)₃] in high yield. The n.m.r. data for the new complexes are reported and discussed.
