Uses
(^+)-2,2'-Bis(diphenylphosphino)-1,1'-binaphthyl plays an essential role in the organic synthesis of enantioselective transformations catalyzed by the complexes of ruthenium, rhodium and palladium. It is also employed in palladium-catalyzed arylamine coupling in the preparation of demethylthiocholchines. It is used with Cu(II) to catalyze the addition of arylsulfonamides to styrenes and olefins.
Uses
2,2'-Bis(diphenylphosphino)-1,1'-dinaphthalene is a powerful chiral auxiliary that is used as a homogeneous catalyst in some asymmetric chemical syntheses. 2,2'-Bis(diphenylphosphino)-1,1'-dinaphthalene is utilized for its high enantioselectivity and is used as a ligand to create coordination complexes.
Reactions
Phosphine Ligand Kit component.
- Useful ligand for palladium-catalyzed carbon-nitrogen bond formation.
- Useful ligand for rhodium-catalyzed C-C bond formation.
- Useful ligand for palladium-catalyzed intramolecular acylation of aryl bromides via C-H activation.
- Used in the preparation of Buchwald third generation precatalyst.
- Used in methoxy directed Rhodium migration.
- Used in Nickel catalyzed C-N cross-coupling reactions.
General Description
Racemic version of BINAP.
Purification Methods
Dissolve the enantiomer in toluene, wash it with 30% aqueous NaOH, three times with H2O, dry (Na2SO4), evaporate to ~15% of its volume and add an equal volume of degassed MeOH. Collect the solid, wash it with MeOH and dry it at 80o/0.005mm for 6hours. Recrystallise it from a 1:1 mixture of toluene/EtOH to optical purity (m 241-242o) [Takaya et al. Org Synth 67 20 1989].
