《Synthesis of sulfonate derivatives of maltol and their biological activity against Phytophthora capsici and Bursaphelenchus xylophilus in vitro》 was written by Tian, Yue-E.; Sun, Di; Yang, Jin-Ming; Che, Zhi-Ping; Liu, Sheng-Ming; Lin, Xiao-Min; Jiang, Jia; Chen, Gen-Qiang. Reference of Thiophene-2-sulfonyl chloride And the article was included in Journal of Asian Natural Products Research in 2020. The article conveys some information:
Sixteen sulfonate derivatives of maltol were synthesized and screened in vitro for their anti-oomycete and nematicidal activity against Phytophthora capsici and Bursaphelenchus xylophilus, resp. Among all the compounds, , , and exhibited the most promising and pronounced anti-oomycete activity against P. capsici than zoxamide, and the EC50 values of 25.42, 18.44, 23.69, and 27.99 mg/L, resp.; compounds , , , and exhibited potent nematicidal activity with LC50 values ranging from 1 to 2 mg/L, especially and showed the best promising and pronounced nematicidal activity, with LC50 values of 1.1762 and 1.2384 mg/L, resp. The experimental process involved the reaction of Thiophene-2-sulfonyl chloride(cas: 16629-19-9Reference of Thiophene-2-sulfonyl chloride)
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. Reference of Thiophene-2-sulfonyl chloride
