Beschreibung

Allgemeine Beschreibung

Verkauf in Zusammenarbeit mit Solvias AG

(R)-1-[(S_P)-2-(Diphenylphosphino)ferrocenyl]ethyldicyclohexylphosphine ((R,S)-josiphos) is a chiral ferrocenyl diphosphine ligand.

Anwendung

It may be used in the preparation of cyclopentadienyliridium complexes, [IrCl(PP)]₂ and [IrCp(PP)]. (Cp= cyclopentadienyl; PP= (R)-1-[(S_P)-2-(diphenylphosphino)ferrocenyl]ethyldicyclohexylphosphine)

Rhodium complex of (R)-(S)-JOSIPHOS can be used as a catalyst for the selective asymmetric hydrogenation of:       

• Z-β-aryl-β-(enamido)phosphonates.     
•  o-alkoxy tetrasubstituted enamides to yield β-amino alcohol analogs with excellent enantiomeric excess.

Verpackung

Bottomless glass bottle. Contents are inside inserted fused cone.
