Product Name:Chloro[(S)-(-)-5,5'-bis(diphenylphosphino)-4,4'-bi-1,3-benzodioxole](p-cymene)ruthenium(II) chloride
English Name:Chloro[(S)-(-)-5,5'-bis(diphenylphosphino)-4,4'-bi-1,3-benzodioxole](p-cymene)ruthenium(II) chloride
CAS No.:944451-29-0
Aliases:Dichloro(p-cymene)((S)-segphos)ruthenium(II), [RuCl(p-cymene)((S)-segphos)]Cl, (S)-Segphos ruthenium catalyst
Molecular Formula:C48H40Cl2O4P2Ru
Physical Properties:Yellow to orange-red crystalline powder. Readily soluble in dichloromethane and chloroform; soluble in acetone, methanol and other organic solvents; slightly soluble in diethyl ether. Fairly stable in air but moisture-sensitive; store sealed under inert atmosphere and protected from light.
Uses:Used as a chiral ruthenium catalyst for asymmetric hydrogenation of ketones, imines and other substrates, as well as asymmetric hydrofunctionalization reactions, providing high enantioselectivity. Also employed in chiral ligand synthesis and mechanistic studies of asymmetric catalysis.
