Abstract

The 1,2,4-triphenylcyclopentadienyl ligand and the CHR carbene ligand, bound respectively to the Co and W atoms in [(η⁵-C₅H₅)W{μ- CBu(t)CC(CO₂Me)=C(CO₂Me)CH}(μPPh₂)Co(η⁵-C₅Ph₃H₂)], are derived from the oligomerisation and cleavage of three molecules of phenylacetylene in the reaction of [(OC)(η⁵-C₅H₅)W{η-C(CO₂Me)CC(C≡CBu(t))(OMe)O}(μ- PPh₂)Co(CO)₂] with this acetylene.
