| | 1,2-Bis(diphenylphosphino)ethane Usage And Synthesis |
| Chemical Properties | white to light yellow crystal powde | | Uses | suzuki reaction | | Uses | 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. | | Definition | ChEBI: 1,2-bis(diphenylphosphino)ethane is a tertiary phosphine and a member of diphosphanes. It has a role as an allergen. | | Purification Methods | Recrystallise it from aqueous EtOH or *C6H6. The dimethiodide, when recrystallised from MeOH has m 305-307o, and the dioxide when recrystallised from toluene or DMF (needles), or *C6H6 (plates) has m 252-254o (276-278o) [Isslieb et al.
