摘要
The synthesis and resolution of the trifluoromethyl-palladacycle, di-mu-chloro-bis(N,N-dimethyl-(2,2,2-trifluoro-1-phenylethyl)amine-2-C,N)palladium(II) are shown. The utility of the complex and its application in the enantiomeric excess determination of alpha-amino acids by F-19 NMR spectroscopy is demonstrated and X-ray diffraction analysis of one of the diastereomeric complexes, trans-{[(R)-phenylglycinato-N,O][(R)-N,N-dimethyl-(2,2,2-trifluoro-1-phenylethyl)amine-C,N]palladium(II)}, is reported.
