(R)-(+)-2,2'-Bis(diphenylphosphino)-1,1'-binaphthyl Structure

(R)-(+)-2,2'-Bis(diphenylphosphino)-1,1'-binaphthyl Chemical Properties

 

BINAP (2,2'-bis(diphenylphosphino)-1,1'-binaphthyl) is an organophosphorus compound. This chiral ligand is widely used in asymmetric synthesis. It consists of a pair of 2-diphenylphosphinonaphthyl groups linked at the 1 and 1´ positions. This C2-symmetric framework lacks a stereogenic atom, but has axial chirality due to restricted rotation (atropisomerism). The barrier to racemization is high due to steric hindrance, which limits rotation about the bond linking the naphthyl rings. The dihedral angle is approximately 90?.

(R)-(+)-2,2'-Bis(diphenylphosphino)-1,1'-binaphthyl Usage And Synthesis
Reaction    

    (R)-BINAP or (R)-Tol-BINAP can be combined with dichloro(1,5-cyclooctadiene)ruthenium to form precursors to NOYORI CATALYST SYSTEMS. These systems exhibit very high catalytic activity and enantioselectivity in the hydrogenation of a wide range of substrates. NOYORI CATALYST SYSTEMS have been shown to effect highly enantioselective hydrogenation of functionalized ketones where the substituents are dialkylamino, hydroxy, siloxy, carbonyl, ester, amide or thioester.


Chemical Properties    white to light yellow crystal powde
Uses    Chiral ligand for metal mediated asymmetric catalysis.
