  摘要：

  Optically active complexes of Zr, Fe, Ni, and nu containing the chiral, menthyl-substituted indenyl ligands (-)-3-menthyl-4,7-dimethylindene and (-)-2-menthylindene are described. Metathetic reaction of the chiral main-group-metal salts of these indenyl systems with the appropriate starting materials of Zr, Fe, and Ni yielded the complexes (pR)(pR)-/(pR)(pS)(1-menthyl-4,7-dimethylindenyl)(2)ZrCl2 (4a/4b), (pR)-/(pS)-(cyclopentadienyl)(1-menthyl-4,7dimethylindenyl)ZrCl2 (5a/5b), (pR)(pR)-/(pR)(pS)-/(pS)(pS)-(1-menthyl(6a/6b/6c), (pR)(pR)-/(pR)(pS)-/(pS)(pS)-(1-menthyl-(7a/7b/7c), (+)-(2-menthylindenyl)(2)Fe (8), and (-)-(2-menthylindenyl)(2)Ni (9). Ru(acac)(3) reacts with (-)-(2-menthylindenyl)lithium (3), yielding (-)-(2-menthylindenyl)(2)Ru (10). Depending on the reaction conditions, compounds 4-7 were formed as mixtures of diastereomers with respect to the planar chirality of the indenyl ring system. The apparent diasteromeric excess varied between 13 and 50% de. The Fe, Ni, and Ru complexes were purified by chromatography via dried alumina under nitrogen. The structures of 4b and 8 were determined by single-crystal X-ray diffractometry.
