Complexes Cu(SPh)(2), Cu(SPh)I and KCu(SPh)(2)(Ph) were observed by in situ electrospray ionization mass spectrometry (ESI-MS) analysis of the copper(i)-catalyzed C-S coupling reaction under catalytic reaction conditions indicating that they are intermediates in the reaction. A catalytic cycle was proposed based on these observations.
在铜（i）催化的 C-S 偶联反应的原位电喷雾电离质谱（ESI-MS）分析中观察到 [Cu(SPh)(2)]-、[Cu(SPh)I]-和 K[Cu(SPh)(2)(Ph)]+复合物，表明它们是反应中的中间体。基于这些观察结果，提出了一个催化循环。
