      Product Detail  


    BINAP is an abbreviation for the organic compound 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl. This chiral ligand is widely used in asymmetric synthesis. It consists of a pair of 2-diphenylphosphinonaphthyl groups linking the 1 and 1' positions (Figure 1). This C2-symmetric framework is free of chiral atoms (see Axial Chirality). Due to spatial site-barriers, the bis-naphthyl ring has a high racemic barrier thus limiting the free rotation of the chemical bond connecting the two naphthyl rings (see blocked rotation isomers). Their naphthalene ring planes form dihedral angles of about 90˚.
