| titleOfInvention | CATALYZING COMPOSITIONS AND THEIR USE IN THE DE-ENRICHMENT OF ENANTIOMERICALLY ENRICHED SUBSTRATES. |
| abstract | A process for de-enriching enantiomerically enriched compositions is provided comprising reacting an enantiomerically enriched composition comprising at least a first enantiomer or diastereomer of a substrate comprising a carbon-heteroatom bond, wherein carbon is a chiral center and the heteroatom is a heteroatom of group V, in the presence of a catalyst system and optionally a reaction promoter to give a product composition comprising first and second enantiomers or diastereomers of the substrate having a carbon-heteroatom bond, the ratio of the second to the first enantiomer or diastereomer in the composition of the product is greater than the ratio of the second to the first enantiomer or diastereomer in the enantiomerically enriched composition; Preferred catalyst systems include a transition metal halide complex of the formula MnXpYr wherein M is a transition metal; X is a halide; Y is an optionally substituted neutral hydrocarbyl complexing group, an optionally substituted perhalogenated hydrocarbyl complex neutral group, or an optionally substituted cyclopentadienyl complexing group; and n, p and r are integers; The reaction promoter is preferably a halide salt. |
