DIPHOSPHINE AND METAL COMPLEXES Russian patent published in 2011 - IPC C07F17/02 

FIELD: chemistry.

SUBSTANCE: invention relates to compounds of formulae I or I', in which radicals R₁ denote a hydrogen atom and R'₁ denotes C₁-C₄-alkyl; X₁ and X₂ each independently denotes a fluoro-phosphine group, where secondary phosphine groups X₁ and X₂ contain hydrocarbon radicals containing 1-22 carbon atoms and can be unsubstituted or substituted, and/or contain heteroatoms selected from groups comprising O, S and N(C₁-C₄-alkyl); R₂ denotes hydrogen; T denotes C-bonded C₃-C₂₀-heteroarylene in which heteroaryl groups, from which heteroarylene is obtained, are pyrrole, N-methylpyrrole, furan, thiophene, indole, N-methylindole, benzofuran, benzothiophene, pyridine, pyrimidine and quinoline; v equals 0; group X₁ in the heteroarylene heterocycle is bonded in the ortho-position relative the T-C* bond; * denotes a mixture of racemic or enantiomerically pure diastereomers or pure racemic or enantiomerically pure diastereomers. The invention also discloses metal complexes, a method producing chiral organic compounds and use of metal complexes for producing chiral organic compounds.

EFFECT: high optical output during hydrogenation of prochiral organic compounds.
