Chlorosulfonyl substituted aromatic heterocyclic compounds, such as 2-chlorosulfonyl[1,2,4]triazolo[1,5-c]pyrimidine compounds, were prepared in good yield by chloroxidation of di(aromatic heterocyclyl) disulfide compounds in a medium containing water, a water-immiscible organic solvent, and a phase transfer catalyst, such at tetrabutylammonium chloride.
氯磺酰基取代的芳香杂环化合物,例如2-氯磺酰基[1,2,4]三唑[1,5-c]嘧啶化合物,通过在含水、不溶于水的有机溶剂和相转移催化剂(如四丁基氯化铵)的介质中氯氧化二(芳杂环基)二硫化物化合物,以良好的产率制备。
