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°.〔Mazhar-ul-Haque, Hasan A. Tayim, Jamil Ahmed, and William Horne "Crystal and molecular structure of triphenylarsine" ''Journal of Chemical Crystallography'' Volume 15, Number 6 / 1985. 〕 This compound is prepared by the reaction of arsenic trichloride with chlorobenzene using sodium as the reducing agent:〔 (article )〕 :AsCl3 + 3 PhCl + 6 Na → AsPh3 + 6 NaCl ==Uses== AsPh3 is the precursor to tetraphenylarsonium chloride, ()Cl, a popular precipitating agent.〔 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「triphenylarsine」の詳細全文を読む スポンサード リンク
