The optical active diphosphine, production of the said diphosphine with the manner which splits the racemic mixture, and use of the said diphosphine

摘要

(57) Abstract This invention regards the optical active diphosphine. This invention regards also the manner which produces aforementioned phosphine with the manipulation which separates the racemic mixture of aforementioned phosphine into optical active isomer. There is with a split manner of the aforementioned racemic mixture which consists of the fact that subject of this invention reacting with the palladium or platinum complex the new optical active bis [1 phospha 2,3 diphenyl 4,5 jimechirunoruborunajien] diphosphine and the bis [1 phospha 2,3 diphenyl 4,5 jimechirunoruborunajien] racemic mixture as a kiraru aid in the organicity solvent, forms the diastereoisomer complex, next optically splits the pure aforementioned complex. As for this invention, the new optical active metal complex which includes aforementioned phosphine and, , unsaturated carboxylic acid and/or with the manipulation which hydrogenates the derivative optical active carboxylic acid and/or it regards with also the use of the aforementioned complex in the manner which produces the derivative.
