Synthesis, structure, and bonding of fulvene complexes of titanium, molybdenum, and tungsten
Abstract
The compounds [M(η-C6H5R)(σ,η5-C5H4CR′2)](M = Mo or W, R = H, R′= Me or Ph; M = W, R = Me, R′= Me or Ph), [W(η-C6H3Me3-1,3,5)(σ,η5-C5H4CPh2)], [Ti(σ,η5-C5H4CPh2)2], and [Ti(σ,η5-C5H4CPh2)2(CO)] are described. The crystal structures of the compounds where M = Mo, R = H, R′= Me or Ph; M = W, R = Me, R′= Me or Ph; and [Ti(σ,η5-C5H4CPh2)2] have been determined and reveal that the exocyclic carbon of the fulvene ligands is strongly bent out of the plane of the C5-ring carbons and bonds directly to the metal. The metal–fulvene bonding is discussed in the light of the structures, the photoelectron spectra, and molecular orbital calculations.
