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. J Chem Soc, Dalton Trans 2145 1986, Boert et al. J Am Chem Soc 109 7781 1987]. [Beilstein 16 H 829, 16 I 431, 16 II 407, 16 III 921, 16 IV 1139.] HIGHLY TOXIC.
