摘要：

Chiral, biphenyl-bridged metallocene complexes of general type biph(3,4-R2C5H2)(2)MCl2 (biph = 1,1'-biphenyldiyl) were synthesized and characterized. For the dimethyl-substituted titanocenes and zirconocenes (R = CH3; M = Ti, Zr), preparations with increased overall yields and an optical resolution method were developed. The bis(2-tetrahydroindenyl) complexes (R,R = (CH2)(4); M = Ti, Zr) were obtained by an alternative synthetic route and characterized with regard to their crystal structures. Syntheses of the phenyl-substituted derivatives (R = C6H5; M = Ti, Zr) and of a chiral, methyl-substituted vanadocene complex (R = CH3; M = V) are also reported. (C) 1997 Elsevier Science S.A.
