Triphenylarsine is an organometallic compound with the formula (C₆H₅)₃As, often abbreviated as AsPh₃ or Ph₃As. It is a white solid that is soluble in organic solvents.
Synthesis[edit | edit source]
Triphenylarsine can be synthesized by the reaction of arsenic trichloride with phenylmagnesium bromide or phenyllithium. The reaction proceeds as follows:
- AsCl₃ + 3 C₆H₅MgBr → As(C₆H₅)₃ + 3 MgBrCl
This method involves the use of Grignard reagents, which are common in the synthesis of organometallic compounds.
Applications[edit | edit source]
Triphenylarsine is used as a ligand in coordination chemistry. It forms complexes with many transition metals, which are often used in catalysis and organic synthesis.
Safety[edit | edit source]
Triphenylarsine is considered toxic, and appropriate precautions should be taken when handling it. It should be stored in a cool, dry place, away from incompatible materials.
