应用

1,2-Dibromoethane-1-sulfonyl fluoride (DESF) is a bench-stable precursor to 1-bromoethene-1-sulfonyl fluoride (BESF), a new and robust connective hub for the Sulfur (VI) fluoride exchange (SuFEx) click reaction. BESF offers similar routes as ethenesulfonyl fluoride (ESF, cat# 746959) but with additional reactivity due to the embedded bromo group.

Treatment of DESF with triethylamine generates BESF in situ, which has been used to synthesize diverse and unprecented sulfonyl fluorides in good-to-excellent yields. As the resulting molecules possess sulfonyl fluoride handles, further SuFEx reactions are also possible. DESF adds another useful tool for conjugation strategies in chemical biology and organic and polymer synthesis.

A regioselective metal-free preparation of 4-fluorosulfonyl 1,2,3-triazoles from organic azides and a hitherto underexplored bromovinylsulfonyl fluoride building block is described. This reaction is very general and was extended to the synthesis of various sulfonates, sulfonamides, and sulfonic acid derivatives of

We demonstrate 1,2-dibromoethane-1-sulfonyl fluoride (DESF) as a bench-stable and readily accessible precursor to the robust SuFEx connector, 1-bromoethene-1-sulfonyl fluoride (BESF). The in situ generation of BESF from DESF opens up several new reaction profiles, including application in the syntheses of

A new fluorosulfonylation reagent 1-bromoethene-1-sulfonyl fluoride was developed (1-Br-ESF). This unique reagent possesses three addressable handles (vinyl, bromide, and sulfonyl fluoride) and has great potential to function as a tris-electrophile and as a sulfur(vi) fluoride exchange (SuFEx) clickable material to
