Recently, sulfonylation reactions using potassium/sodium metabisulfite as the sulfur dioxide surrogate have been developed rapidly. In most cases, the transformations go through radical processes with the insertion of sulfur dioxide under mild conditions. Additionally, transition metal catalysis is applied in the reactions for the synthesis of sulfonyl-containing compounds. Among the approaches, photoinduced conversions under visible light or ultraviolet irradiation are also involved. In this updated report, the insertion of sulfur dioxide from potassium metabisulfite or sodium metabisulfite is summarized.
近年来，使用亚硫酸氢钾/亚硫酸钠作为二氧化硫替代物的磺酰化反应迅速发展。在大多数情况下，这些转化是通过自由基过程在温和条件下插入二氧化硫进行的。此外，过渡金属催化也应用于含磺酰基化合物的合成反应中。在这些方法中，可见光或紫外光照射下的光诱导转化也包括在内。在本更新报告中，总结了亚硫酸氢钾或亚硫酸钠中二氧化硫的插入。
