Note: (R,S)-BnBp yttrium complexes are those derived from (R)-(+)-binaphthol and having 5 metallocene stereochemistry. (S,R)-BnBp complexes are derived from (S)-(-)-binaphthol and have R metallocene stereochemistry. (±)-BnBp yttrium complexes, derived from racemic binaphthol, contain exclusively the diastereomers indicated for the resolved complexes.
