In 2022,Song, Xuyan; He, Yunlu; Wang, Bo; Peng, Sanwen; Pan, Xi; Wei, Min; Liu, Qiang; Qin, Hua-Li; Tang, Haolin published an article in Tetrahedron. The title of the article was 《Synthesis of aryl sulfonyl fluorides from aryl sulfonyl chlorides using sulfuryl fluoride (SO2F2) as fluoride provider》.Name: Thiophene-2-sulfonyl chloride The author mentioned the following in the article:
A highly efficient method for the synthesis of aryl sulfonyl fluorides ArSO2F [Ar = 4-MeC6H4, 4-PhC6H4, 4-ClC6H4, etc.] was developed from aryl sulfonyl chlorides using SO2F2 as fluoride source in up to 98% isolated yield under mild conditions. Gram scale experiments were also conducted, revealing the good practicality of this new protocol. In the part of experimental materials, we found many familiar compounds, such as Thiophene-2-sulfonyl chloride(cas: 16629-19-9Name: 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. Name: Thiophene-2-sulfonyl chloride
