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.
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(底物、抗衡离子、溶剂)中每个组分对衰减过程的影响。研究发现,底物(炔烃/丙二烯/烯烃)诱导的金(I)歧化反应可能在衰减过程中起关键作用。我们的机理得到了动力学、XPS、伏安法研究和高分辨率 ESI-MS 数据的支持。
