Formation of diastereomers is precluded when biphenyl-bridged bis(cyclopentadienyls) and transition-metal halides combine to give chiral ansa-metallocenes. These must be symmetrically substituted. Syntheses and X-ray diffraction analyses are reported for four biphenyl-bridged ansa-metallocenes: titanocene dichlorides 17 and 22, zirconocene dichloride 18, and ferrocene 13.
