| TRIPHENYLARSINE Usage And Synthesis |
| Reaction |
- Useful as a ligand in Stille coupling reactions.
- Synthesis of functionalized cyclopropanes from the reaction between acetylenic esters and C-H acids.
- Rh-complex catalyzed addition reactions of chloroacetyl chlorides to alkynes.
| | Chemical Properties | COLOURLESS TO SLIGHTLY YELLOW CRYSTALLINE SOLID | | Uses | Triphenylarsine is used in certain metal-catalyzed coupling reactions. It is a precursor to tetraphenylarsonium chloride a popular precipitating agent. | | Purification Methods | Recrystallise Ph3As from EtOH or aqueous EtOH [Dahlinger et al.
