摘要：
[GRAPHICS] The ionic CDA [PtCl3(C2H4)](-)[(S,S)-(1-NpMeCH)(2)NH2](+) produces, on exchange of its coordinated ethylene by chiral trisubstituted allenes, diastereoisomeric mixtures originating distinct Pt-195 NMR resonances for the complexed enantiomers, thus allowing the determination of the enantiomeric purity, A reproducible correlation between relative positions of platinum signals due to the complexed enantiomers and their absolute configuration has been found.
