Enantioselektive Pi-Komplexierung durch intramolekulare Chiralitätsübertragung aus CpTi-Aminosäure-Komplexen
… of chiral CpTiL*-complexes where L* = amino acid, lactic acid or phenylethylamine. With these complexes the possibility for the preparation of enantiomerically enriched "titanocenes" [CpCppcTiCl2], where Cppc is a prochiral cyclopentadienide, was explored. In cyclopentadienylation L* acts as …
