Abstract
[GRAPHICS] The ionic CDA [PtCl3(C2H4)](-)[(S,S)-(1-NpMeCH)(2)NH2](+) produces, on exch ange of its coordinated ethylene by chiral trisubstituted allenes, diastere oisomeric mixtures originating distinct Pt-195 NMR resonances for the compl exed enantiomers, thus allowing the determination of the enantiomeric purit y, A reproducible correlation between relative positions of platinum signal s due to the complexed enantiomers and their absolute configuration has bee n found.
