Optical Stereoisomers of Geometric Isomers of the Octahedral Complex TiF4[Ph2P(O)CH2CH(OH)Me)]2 in CH2Cl2

Resumo

Some peculiarities of the effect of enantiomers of the monodentate ligand on the stereoisomerism of the mixed octahedral tetrafluoride complexes of d⁰-transition metals are established by the ¹⁹F{¹Н} and ³¹Р{¹Н} NMR methods for the complex formation of TiF₄ with Ph₂P(O)CH₂CH(OH)Me (L) having the asymmetric carbon atom in the aliphatic hydrocarbon radical and being a racemic mixture of enantiomers in СН₂Сl₂. The compositions of the complexes formed in solutions are determined. The conclusion about the relative stereochemical configuration of the chiral and meso-stereoisomers of the geometric isomers of the TiF₄L₂ octahedral complex is based on an analysis of the ¹⁹F NMR spectra using the heterotropic concept.
