Ethoxy Group Scrambling in the Sterically Restricted Ethoxysulfonium Salts, 1-(Methylethoxysulfonio)-9-(methylthio)dibenzothiophene and Its Analogous Compounds
摘要:
1-(methylethoxysulfonio)-9-(methylthio)dibenzothiophene 的乙氧基迁移是在 25 °C 下通过 1H-NMR 确定的。在相同的条件下,1-(甲乙氧磺酰基)-8-(甲硫基)萘也发生了类似的重排。在 2-(甲基乙氧基磺酰基)-2′-(甲硫基)联苯中,乙氧基扰乱没有进行。
