An extensive experimental study of the mechanism of gold(I)‐catalyzed hydroalkoxylation of internal alkynes has been conducted by using NMR spectroscopy. This study was focused on the organogold intermediates, observations of actual catalytic intermediates in situ, and the reaction kinetics that are involved in this reaction. Based on the experimental results, a complete mechanistic picture was established
使用NMR光谱对金(I)催化的内部炔烃加氢烷氧基化机理进行了广泛的实验研究。这项研究的重点是有机金中间体,原位实际催化中间体的观察以及该反应涉及的反应动力学。根据实验结果,建立了完整的机理图,包括解释了稀有物种的作用的循环和非循环过程。我们已经表明,内部炔烃的金催化加氢烷氧基化反应只需要一个金原子就可以进行催化循环,这证明了有关协同金催化作用的最新假设。
