Chemical Properties

white powder

Uses

For the in situ preparation of chiral hydrogenation catalysts.

General Description

(-)-2,3-O-Isopropylidene-2,3-dihydroxy-1,4-bis(diphenylphosphino)butane is a C2 chelating diphosphine ligand for transition metal complexes during asymmetric catalysis.

Purification Methods

It has been recrystallised from *C6H6/pet ether. After 2 recrystallisations from EtOH, it was pure by TLC on silica gel using Me2CO/hexane as solvent.
