Abstract
Effect of enantiomers of a monodentate ligand on the stereoisomerism of mixed octahedral cis-tetrafluoro complexes of d0 transition metals has been studied by 19F{1H} and 31P{1H} NMR by the example of TiF4 complexation in CH2Cl2 with Ph2P(O)CH2CH(OH)Me (L) containing asymmetric carbon atom in the aliphatic hydrocarbon group that constitutes a racemic mixture of enantiomers. Composition of complexes formed in solution has been determined, conclusion has been drawn on the relative stereochemical configuration of the chiral and meso stereoisomers of octahedral complex cis-TiF4L2 on the basis of analysis of 19F NMR spectra, using the heterotropism concept.
