| Hazard Information | Back Directory | [Uses]
Dichloro[2,3-O-isopropylidene-2,3-dihydroxy-1,4-
bis(diphenylphosphino)butane]palladium(II) (also named (DIOP)PdCl2) is a chiral catalyst used in asymmetric hydrocarboxylation or hydroalkoxycarbonylation reactions, allylation
of β-diketones or β-keto esters, double carbonylation, cross-coupling reactions, preparation of optically
active Pd0 derivatives and their subsequent reactions. | [Preparation]
Dichloro[2,3-O-isopropylidene-2,3-dihydroxy-1,4-
bis(diphenylphosphino)butane]palladium(II) prepared from commercially available Palladium(II) Chloride and (-)-(2R,3R)-(2,3-OIsopropylidene)-2,3-dihydroxy-1,4-bis(diphenylphosphino)butane in ether, or by treating a stoichiometric amount of (-)-(2R,3R)-DIOP in ethanol with Li2PdCl4 in water, or from (+)-(2S,3S)-DIOP and
Pd(PhCN)2Cl2 in benzene or acetone. | [storage]
Dichloro[2,3-O-isopropylidene-2,3-dihydroxy-1,4- bis(diphenylphosphino)butane]palladium(II) is relatively stable to air oxidation.
