Abstract
Three ortho-palladated complexes were tested as chiral derivatizing ag ents for enantiomeric excess determination of monodentate P--chiral p hosphines by P-31 NMR analysis. The complexes containing a bulky subst ituent at the alpha-C- - 1e or an N-*-stereocentre 1d are shown to be more efficient as compared to known N-achiral alpha-methyl substitute d analogues. The structure and stereochemistry of the new dimeric comp lex (S-c)-1e was established by X-ray analysis. (C) 1997 Published by Elsevier Science Ltd.
