Triphenylarsine is the chemical compound with the formula As(C6H5)3. This organoarsenic compound, often abbreviated AsPh3, is a colorless crystalline solid that is used as a ligand and a reagent in coordination chemistry and organic synthesis.
This compound is prepared by the reaction of arsenic trichloride with chlorobenzene using sodium as the reducing agent:[1]
- AsCl3 + 3 PhCl + 6 Na → AsPh3 + 6 NaCl
[edit] Uses
AsPh3 is the precursor to tetraphenylarsonium chloride, [AsPh4]Cl, a popular precipitating agent.[1]
AsPh3 forms complexes with low valent metals that are analogous to the corresponding triphenylphosphine derivatives, such as IrCl(CO)(AsPh3)2 and RhCl(AsPh3)3.
