Sulfonyl fluorides are valuable synthetic motifs for a variety of applications, among which sulfur(VI) fluoride exchange-based “click chemistry” is currently the most prominent. Consequently, the development of novel and efficient synthetic methods to access these functional groups is of great interest. Herein, we report a mild and environmentally benign electrochemical approach to prepare sulfonyl
磺酰氟是具有多种应用价值的合成基序,其中基于硫 (VI) 氟化物交换的“点击化学”是目前最突出的。因此,开发新的和有效的合成方法来访问这些官能团是非常有趣的。在此,我们报告了一种温和且环境友好的电化学方法,使用硫醇或二硫化物作为广泛可用的起始材料,结合 KF 作为廉价、丰富和安全的氟化物来源来制备磺酰氟。不需要额外的氧化剂或额外的催化剂,由于反应条件温和,反应显示出广泛的底物范围,包括各种烷基、苄基、芳基和杂芳基硫醇或二硫化物。
