摘要：

The use of a C2-symmetric 2,2'-dimethyl-1,1'-binaphthyl bridge between two 1-indenyl ligands, readily obtained from known, enantiomerically pure 2,2'-bis(bromomethyl)-1,1'-binaphthyl, suppresses the formation of an undesired meso orientation of ansa-bis(indenyl) metal complexes of titanium and zirconium dichlorides 3 and favors the desired isolation of one of the possible two C2-symmetric isomers in enantiomerically enriched form, avoiding the need for resolution of the metal complexes.
