    • 1)(diene), the η3-benzyl ligand may be oriented in two fashions relative to the linked amidocyclopentadienyl ligand to give "prone" and "supine" isomers; see ref 11b. In the case of complex 9c, the phenyl ring is oriented toward the amido ligand, similar to the observation that linked tert-butylamido cyclopentadienyl titanium complexes of branched dienes such as isoprene and 1,3-pentadiene prefer the "supine" isomer (with the "cup" of the diene oriented toward the cyclopentadienyl ligand), whereas unbranched dienes prefer the "prone" isomer (with the "cup" of the diene oriented toward the amido ligand).
