Yang, Jiajun; Li, Guodong; Yu, Ke; Xu, Bo; Chen, Qianjin published an article in 2022. The article was titled 《Electrochemical Sulfonylation-Induced Lactonization of Alkenes: Synthesis of Sulfonyl Phthalides》, and you may find the article in Journal of Organic Chemistry.HPLC of Formula: 16629-19-9 The information in the text is summarized as follows:
An electrochem. cascade sulfonylation and lactonization process of alkenes and a most widely used arylsulfonylation reagent-sulfonyl hydrazines-was developed for the first time. This electrochem. sulfonyl lactonization avoids the use of toxic metal catalysts or stoichiometric oxidants and was carried out under mild conditions. The target product γ-sulfonylated phthalides with broad and excellent substrate tolerance were achieved. The experimental process involved the reaction of Thiophene-2-sulfonyl chloride(cas: 16629-19-9HPLC of Formula: 16629-19-9)
Thiophene-2-sulfonyl chloride(cas: 16629-19-9) is a member of sulfonyl chlorides. Sulfonyl chlorides are reactive sulfonic acid derivatives similar in properties and reactivity to acid chlorides of carboxylates. The sulfonic acid group, however, is a highly hindered molecule, containing a tetrahedral configuration of substituents. HPLC of Formula: 16629-19-9
