本文首次对阳离子金的失活进行了详细的实验研究，考察了反应体系中各组分（底物、反离子、溶剂）对其失活过程的影响。发现底物（炔/烯/烯烃）诱导的金(I)歧化可能在衰变过程中起关键作用。我们的机制得到了动力学、XPS、伏安研究和高分辨率ESI-MS数据的支持。
The first detailed experimental study of the deactivation of cationic gold was conducted, and the influence of each component in the reaction system (substrate, counterion, solvent) on the decay process was examined. It was found that a substrate (alkyne/allene/alkene)-induced disproportionation of gold(I) may play a key role in the decay process. Our mechanism is supported by kinetic, XPS, voltammetry studies, and high-resolution ESI-MS data.
