Anwendungen

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.

Bemerkungen

Air sensitive. Store away from oxidizing agents. Keep the container tightly closed and place it in a cool, dry and well ventilated condition.
