Preparation of optically active peralkyldiphosphines and their use, as the rhodium(I) complex, in the asymmetric catalytic hydrogenation of ketones

Two types of the optically active peralkyldiphosphine, 2,3-O-isopropylidene-2,3-dihydroxy-1,4-bis(dialkylphosphino)butane (Rdiop 3) and N-(N'-substituted carbamoyl)-4-dicyclohexylphosphino-2-dicyclohexylphosphinomethylpyrrolidine (R-Cycapp 8), have been p

NEW ENTRY TO THE PREPARATION OF CHIRAL BIS(DICYCLOHEXYLPHOSPHINO)ALKANE DERIVATIVES. USE FOR RHODIUM-CATALYZED HYDROGENATION OF CARBONYL COMPOUNDS

Conversion has been achieved of two representative chiral diphosphines, (-)-DIOP and (S,S)-Chiraphos, into the corresponding bis(dicyclohexylphosphino)alkane derivatives, the latter being used for chiral ligands of the rhodium(I) catalyst in the homogeneous hydrogenation of prochiral carbonyl compounds.
