white powder | [Uses]
It is employed as a ligand for the in situ preparation of chiral hydrogenation catalysts. It also finds it application for the in situ preparation of chiral hydrogenation catalysts, ligand for Rh(I)-catalyzed asymmetric hydrogenation of enamides, 1,4-disilylation of α,β-unsaturated ketones, Heck reaction of alkenyl iodides, and hydroformylation of olefins. | [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.
