This review is focused on the recent advances in the chemistry of sulfur dioxide fixation through a radical process. Diverse sulfonyl compounds can be obtained efficiently under mild conditions. In general, aryl radicals, vinyl radicals, alkyl radicals, and nitrogen-centered radicals can react with sulfur dioxide, giving rise to sulfonyl radical intermediates. The resulting sulfonyl radicals can be captured by nucleophiles, olefins, and alkynes. The sources of aryl radicals from aryldiazonium salts, aryl halides, and diaryliodonium salts are demonstrated. It is believed that more amazing SO₂-based achievements will be developed in the near future.

通过自由基过程插入二氧化硫：生产磺酰基化合物的有效途径

这篇综述集中在通过自由基过程固定二氧化硫的化学方面的最新进展。在温和的条件下可以有效地获得各种磺酰基化合物。通常，芳基，乙烯基，烷基和以氮为中心的基团可以与二氧化硫反应，从而产生磺酰基基团的中间体。所得的磺酰基自由基可以被亲核试剂，烯烃和炔烃捕获。证明了来自芳基重氮盐，芳基卤化物和二芳基碘鎓盐的芳基自由基的来源。相信不久的将来将会开发出更多基于SO ₂的惊人成就。
