catalyzed the reductive dithioacetalization of a variety of aromatic and aliphatic carboxylic acids with 1,2-ethanedithiol or 1,3-propanedithiol leading to the one-pot preparation of either 1,3-dithiolane derivatives or a 1,3-dithiane derivative. Also, the intact indium catalyst continuously catalyzed the subsequent oxidative desulfurization of an in situ formed 1,3-dithiolane derivative, which led to
在这项研究中,InI 3 -TMDS(1,1,3,3-四甲基二硅氧烷)还原系统有效催化了各种芳香族和脂肪族羧酸与1,2-乙二硫醇或1,3-丙二酚的还原二硫缩醛化反应,从而导致一锅制备1,3-二硫杂环戊烷衍生物或1,3-二硫杂环己烷衍生物。同样,完整的铟催化剂连续催化原位形成的1,3-二硫杂环戊烷衍生物的氧化脱硫,从而导致相应醛的制备。
