Synthesis of aryl sulfonyl fluorides from aryl sulfonyl chlorides using sulfuryl fluoride (SO2F2) as fluoride provider was written by Song, Xuyan;He, Yunlu;Wang, Bo;Peng, Sanwen;Pan, Xi;Wei, Min;Liu, Qiang;Qin, Hua-Li;Tang, Haolin. And the article was included in Tetrahedron in 2022.Product Details of 454-65-9 This article mentions the following:
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 experiment, the researchers used many compounds, for example, 3-Bromobenzene-1-sulfonyl fluoride (cas: 454-65-9Product Details of 454-65-9).
3-Bromobenzene-1-sulfonyl fluoride (cas: 454-65-9) belongs to organobromine compounds. Bromo compounds are employed in a variety of metal-catalyzed coupling reactions. They are also ideal candidates for the synthesis of Grignard reagents that have wide-applicability in organic synthesis. Many of the alkyl bromine derivatives are excellent alkylating agents since bromides are good leaving groups. Tribromides, like tetrabutylammonium tribromide, are used as a solid source of bromine. N-bromosuccimide (NBS) is used for the selective bromination of allylic bonds.Product Details of 454-65-9
