Electrosynthesis has recently attracted more and more attention due to its great potential to replace chemical oxidants or reductants in molecule-electrode electron transfer. Sulfonyl compounds such as sulfonyl hydrazides, sulfinic acids (and their salts), sulfonyl halides have been discovered as practical precursors of several radicals. As electrochemical redox reactions can provide green and efficient pathways for the activation of sulfonyl compounds, studies for electrosynthesis have rapidly increased. Several types of radicals can be generated from anodic oxidation or cathodic reduction of sulfonyl compounds and can initiate fluoroalkylation, benzenesulfonylation, cyclization or rearrangement. In this Review, we summarize the electrosynthesis developments involving sulfonyl compounds mainly in the last decade.
由于电合成在分子-电极电子转移中具有替代化学氧化剂或还原剂的巨大潜力，因此最近受到了越来越多的关注。磺酰基化合物（如磺酰肼、亚磺酸（及其盐）、磺酰卤）已被发现是几种自由基的实用前体。由于电化学氧化还原反应可以为磺酰化合物的活化提供绿色高效的途径，因此电合成的研究迅速增加。可以通过磺酰化合物的阳极氧化或阴极还原产生几种类型的自由基，并引发氟烷基化、苯磺酰化、环化或重排。在这篇综述中，我们总结了过去十年中主要涉及磺酰化合物的电合成发展。
