Description

CAS: 98327-87-8 | C44H32P2 | 622.69 g/mol

(±)-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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
