(S)-1-[(R)-2-(DIPHENYLPHOSPHINO)FERROCENYL]-ETHYLDI-TERT.-BUTYLPHOSPHINE Usage And Synthesis

Reaction

Ferrocenylphosphine ligands of the type cpFecp(PR2)(*CH(CH3)PR'2) are a class of asymmetric ligands developed at Solvias in Basel, Switzerland . Ligands of this type are currently used industrially in the stereoselective synthesis of commercial products. A unique feature of these bidentate ligands is the presence of a fixed phosphine moiety and a stereogenic, functionalized side chain, which can be easily modified to accommodate electronic and steric requirements. Based on a versatile synthetic procedure starting with optically active ferrocenes of the type cpFecp(PR2)(*CH(CH3)X) [X = OAc or NR2], a variety of donor atoms can be introduced into the side chain. These ferrocene based phosphine ligands have wide application in the stereoselective hydrogenation of substituted acetamidoacrylates, enol acetates, β-ketoesters and simple alkenes.
Useful as a ligand in Pd-catalyzed C-N bond-forming reactions.
Pd-catalyzed enantioselective alkylative desymmetrization of meso-succinic anhydrides.
Asymmetric hydrogenation of ketones and phosphinylketimines.
Michael addition of Grignard reagents to ",$-unsaturated esters and thioesters.
Boration of ",$-unsaturated esters and nitriles.
Reaction of aryl halides with ammonia.
Cu-catalyzed reduction of activated C=C bonds with PMHS.
Regio- and enantioselective hydroboration of vinyl arenes.
Rh-catalyzed asymmetric ring-opening reactions of oxabicyclic alkenes.
1,2-Migrations in Pd-catalyzed Negishi couplings with JosiPhos ligands.
