摘要
硫鎓盐是具有三个碳硫键的带正电荷的最重要四价硫化合物之一.由于硫鎓盐具有较高的化学稳定性、容易制备、结构多样、丰富的反应性等优点,其作为反应底物在有机合成中得到了广泛应用.近年来,可见光促进的有机合成方法学引起了研究者极大的兴趣.总结了各种硫鎓盐试剂在可见光诱导的自由基型反应中的研究进展,介绍了各类C—C键和C—X(X=B,N,O,S,Se,Te,F,Cl,I)键的形成反应,并对部分反应的适用范围和机理进行了讨论.
Sulfonium salts are one of the most important class of organosulfur(IV)compounds which have a positive charge on the sulfur center with three C—S bonds.Because of their bench-stable,easy synthesis,broad structural diversity,and rich reactivity,sulfonium salts are playing a significant role in synthetic chemistry.In recent years,visible-light promoted photoredox catalysis is rapidly developing into a powerful tool for organic synthesis.In this paper,the recent advances of different sulfonium salts in the radical type reactions induced by visible light are summarized.The formation reactions of C—C bond and C—X(X=B,N,O,S,Se,Te,F,Cl,I)bonds are introduced,and the applicable scope and mechanism of some reactions are also discussed.
