This review compiles and summarizes approaches to the preparation of heterocyclic systems containing sulfur atoms based on the reactions of disulfur dichloride which acts as an electrophilic reagent. It is shown that as a result of these transformations heterocycles with different numbers of sulfur atoms can be synthesized: 1,2,5-thiadiazoles, 1,2- and 1,4-thiazines, 1,2-dithiols, 1,2,3-dithiazoles, 1,2,3,4,5-pentathiepines, 1,2,3,4,5,6,7-heptathiocanes, and many others. The yields of the products of these reactions depend to a significant extent on the ratio of the reactants, the nature of the solvent, the base used, and the temperature. The exceptional role of disulfur dichloride in the synthesis of various sulfur-containing heterocycles is shown.

二氯化二硫的亲电加成反应合成含硫杂环

本文综述和总结了基于作为亲电子试剂的二氯化二硫的反应制备含硫原子杂环体系的方法。结果表明，由于这些转变，可以合成具有不同硫原子数的杂环：1,2,5-噻二唑，1,2-和1,4-噻嗪，1,2-二硫醇，1,2， 3-二噻唑，1,2,3,4,5-戊硫平，1,2,3,4,5,6,7-七硫代庚烷，以及许多其他化合物。这些反应的产物的收率在很大程度上取决于反应物的比例，溶剂的性质，所用的碱和温度。显示了二氯化二硫在各种含硫杂环的合成中的特殊作用。
