A new method for the enantiomeric excess determination of chiral trisubstituted allenes by 195Pt NMR of trans-dichloro[(S)-α-methylbenzylamine](allene)platinum(II) complexes
Abstract
The formation of diastereoisomeric complexes trans-dichloro[(S)-α-methylbenzylamine](allene)platinum(II) and detection by 195Pt NMR of their concentrations in CDCl3 solution allow the enantiomeric purity of chiral trisubstituted allenes to be determined easily.
