On the high efficiency of cis-dichloro [(S)-alpha-methylbenzylamine](ethylene)platinum(II) as chiral derivatizing agent for the determination of the enantiomeric composition of chiral unsaturated ethers by Pt-195-NMR spectroscopy: a spectroscopic conformational and configurational characterization in solution of diastereoisomeric complexes cis-dichloro[(S)-alpha-methylbenzylamine][(S)- and (R)-3-phenyl-3-methoxybut-1-ene]platinum(II)

The stereochemistry in solution of the diastereoisomeric complexes cis-dich loro[(S)-alpha-methylbenzylamine][(S)- and (R)-3-phenyl-3-methoxybut-1-ene] platinum(II) has been determined by H-1-NMR spectroscopy: in the two specie s the ethereal ligand is involved by its oxygen atom in the formation of an interligand O ... H-N hydrogen bond with the amine. The remarkable differe ntiation of the Pt-195 resonances is due to the different positions of amin e substituents with respect to the metal.
