Abstract
The chiral ansa-titanocene derivative 1,3-propanediylbis(4,5,6,7-tetrahydro-1-indenyl)titanium(IV) dichloride has been prepared by reaction of the dilithium salt of 1,3-bis(indenyl)propane with TiCl4 and subsequent hydrogenation. The product has been shown by an X-ray diffraction study to be the R,S metal-ring linkage isomer; in this trimethylene-bridged ansa-metallocene the axial symmetry previously observed for te ethylene-bridged congener is destroyed by a non-symmetric location of the (CH2)3 bridge.
