Thiirenium ions generated and accumulated by low-temperature electrochemical oxidation of disulfides in the presence of alkynes were successfully observed by low-temperature NMR, Raman, and mass spectroscopies and were found to be stable at temperatures below −40 °C. The thiirenium ions showed ambident reactivity toward subsequently added nucleophiles to give either disubstituted alkenes or alkynes
通过低温 NMR、拉曼光谱和质谱法成功观察到在炔烃存在下通过二硫化物的低温电化学氧化产生和积累的硫鎓离子,并发现在低于 -40 °C 的温度下是稳定的。取决于亲核试剂的性质,硫鎓离子对随后添加的亲核试剂显示出中间反应性,以产生双取代的烯烃或炔烃。PhSSPh 阳极氧化 PhS Nu
