Product Name:(S)-(-)-2,2'-Bis(diphenylphosphino)-1,1'-binaphthyl
English Name:(S)-(-)-2,2'-Bis(diphenylphosphino)-1,1'-binaphthyl
CAS No.:76189-56-5
Aliases:(S)-BINAP, (S)-(-)-Binaphthyldiphenylphosphine, S-(-)-2,2'-Bis(diphenylphosphino)-1,1'-binaphthalene
Molecular Formula:C44H32P2
Physical Properties:White to off-white crystalline powder, soluble in dichloromethane, chloroform, toluene and other organic solvents, insoluble in water. Optically active, relatively stable in air, but should be stored sealed and protected from light.
Uses:Used as a chiral ligand in asymmetric synthesis, particularly in rhodium- and ruthenium-catalyzed asymmetric hydrogenation reactions, as well as in asymmetric carbon-carbon coupling reactions. It is an important ligand for the preparation of chiral pharmaceuticals and fine chemicals.
Technical Specifications:
Assay not less than 98%
Optical purity not less than 99% ee
Melting point 283-288°C
Specific rotation [α]D20 = -230° (c=0.3, toluene)
