The mechanism of gold(I)-thiolate, disulfide exchange was investigated by using initial-rate kinetic studies, 2D (1H–1H) ROESY NMR spectroscopy, and electrochemical/chemical techniques. The rate law for exchange is overall second order, first order in gold(I)-thiolate and disulfide. 2D NMR experiments show evidence of association between gold(I)-thiolate and disulfide. Electrochemical/chemical investigations
通过使用初始速率动力学研究,2D(1 H– 1 H)ROESY NMR光谱学和电化学/化学技术,研究了硫醇金(I),二硫键交换的机理。对于交换的速率定律是整体二阶,黄金一阶(我)-thiolate和二硫化物。二维NMR实验表明,硫醇金(I)与二硫化物之间存在缔合的证据。电化学/化学研究未显示出游离硫醇盐的证据,并且与涉及在金(I)-硫醇盐,二硫化物交换过程中形成[Au–S,S–S],四心金属环中间体形成的机制是一致的。
