Triphenylarsine

TriphenylboraneTriphenylphosphineTriphenylstibineTriphenylarsine 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. The molecule is pyramidal with As-C distances of 1.942–1.956 Å and C-As-C angles of 99.6–100.5°. Triphenylarsine is the chemical compound with the formula As(C6H5)3.

The molecule is pyramidal with As-C distances of 1.942–1.956 Å and C-As-C angles of 99.6–100.5°. This compound is prepared by the reaction of arsenic trichloride with chlorobenzene using sodium as the reducing agent: Reaction of triphenylarsine with lithium gives lithium diphenylarsenide: Triphenylarsine is the precursor to tetraphenylarsonium chloride, Cl, a popular precipitating agent. AsPh3 forms metal complexes with metals. Most are analogues of the corresponding triphenylphosphine derivatives. Examples include IrCl(CO)(AsPh3)2, RhCl(AsPh3)3, and Fe(CO)4(AsPh3).
