Applications
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.

Solubility
Soluble in acetone, methanol and alcoholic hydrochloric acid.

Notes
Air sensitive. Incompatible with strong oxidizing agents.
