chemo-selective electrochemical oxidation of thioethers to sulfoxides and sulfones was developed. The hydrogen bonding network generated from hexafluoro-2-propanol (HFIP) and acetic acid (AcOH) plays an important role in the modulation of oxidation potential. The hydrogen bonding network complexes strongly with the sulfoxide, making it less prone to further oxidation. Therefore, thioethers can be selectively
开发了一种高效的硫醚化学选择性电化学氧化为亚砜和砜的方法。由六氟-2-丙醇(HFIP)和乙酸(AcOH)生成的氢键网络在氧化电位的调节中起重要作用。氢键网络与亚砜牢固地络合,使其不易进一步氧化。因此,硫醚可以被选择性地电化学氧化成亚砜,并且过氧化可以被最小化。此外,密度泛函理论(DFT)计算和循环伏安法实验支持了这种通过氢键进行的氧化调节。
