三苯基磷氯金的电化学合成

Electrochemical Synthesis of Chloro(triphenylphosphine) gold

以高纯金为牺牲阳极,在三苯基磷与浓盐酸的乙腈溶液中,用电化学方法合成了三苯基磷氯金(Au(PPh3)Cl),并经适当的纯化处理获得了Au(PPh3)Cl白色针状晶体。元素分析、红外光谱和X射线衍射分析结果表明,所制备的产物为Au(PPh3)Cl纯相,同时还对Au(PPh3)Cl电化学合成机理及相关实验条件的影响进行了讨论。

Electrochemical method was employed to synthesize chloro （triphenylphosphine）gold （Au （ PPh3 ） Cl）, which was carried out by using ultra pure gold as anode in an acetonitrile solution containing triphenylphosphine and hydrochloric acid. Needle -like white crystal powders were obtained after purifi- cation, which was identified as pure Au（ PPh3 ）Cl according to the elementary analysis, FT- IR and X- ray diffraction. The reaction mechanism on the formation of Au （ PPh3 ） Cl and the effect of experimental conditions were also discussed.
