Abstract
By a combination of kinetic and theoretical studies it is concluded that gold is intrinsically active to perform the Sonogashira coupling reaction between phenylacetylene and iodobenzene. The presence of Pd impurities is not mandatory for catalyst activity.
摘要
通过动力学和理论研究的结合，可以得出结论，金本身就具有活性，可以进行苯乙炔和碘苯之间的 Sonogashira 偶联反应。钯杂质的存在对于催化剂的活性不是必需的。
