1.1'-Binaphthyl-2.2'-diphemyl phosphine Chemical Properties,Usage,Production

Chemical Properties

1.1'-Binaphthyl-2.2'-diphemyl phosphine is White to light beige powder

Uses

  1. racemic-2,2'-Bis(diphenylphosphino)-1,1'-binaphthyl ( (+/-)-BINAP ) is an essential role in the organic synthesis of enantioselective transformations catalyzed by the complexes of ruthenium, rhodium and palladium.
  2. It is also employed in palladium-catalyzed arylamine coupling in the preparation of demethylthiocholchines.
  3. used with Cu(II) to catalyze the addition of arylsulfonamides to styrenes and olefins.

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.

  1. Useful ligand for palladium-catalyzed carbon-nitrogen bond formation.
  2. Useful ligand for rhodium-catalyzed C-C bond formation.
  3. Useful ligand for palladium-catalyzed intramolecular acylation of aryl bromides via C-H activation.
  4. Used in the preparation of Buchwald third generation precatalyst.
  5. Used in methoxy directed Rhodium migration.
  6. 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].
