Description

CAS: 1663-45-2 | C26H24P2 | 398.43 g/mol

1,2-Bis(diphenylphosphino)ethane is a bidendate ligand used in coordination chemistry to prepare metal complexes. It is involved in the metal-catalyzed allylic alkylation and decarboxylation of allylic esters. It is also used in 1,3-diene synthesis. Further, it is used in cycloaddition reactions and carbonylation reactions. In addition to this, it is used to prepare bis(dicyclohexylphosphino)ethane by hydrogenation.

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.
