Soluble in acetone, methanol and alcoholic hydrochloric acid.


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.


Air sensitive. Incompatible with strong oxidizing agents.

Has also been used as an alternative to PPh3 for the halodehydroxylation of alcohols, e.g. in combination with Hexachloroethane, L14297, alkyl chlorides are formed; the phosphine oxide by-product can readily be separated by filtration: Tetrahedron Lett., 42, 2459 (2001).
