Aryl sulfonyl fluoride synthesis organophotocatalytic fluorosulfonylation of diaryliodonium salts.

A mild and efficient synthesis of various aryl sulfonyl fluorides from diaryliodonium salts under organophotocatalysis a radical sulfur dioxide insertion and fluorination strategy is presented. Diaryliodonium salts are used as aryl radical precursors, the 1,4-diazabicyclo[2.2.

Aliphatic Sulfonyl Fluoride Synthesis via Decarboxylative Fluorosulfonylation of Hypervalent Iodine(III) Carboxylates.

We disclose herein a photocatalytic decarboxylative fluorosulfonylation reaction of various hypervalent iodine(III) carboxylates in combination with 1,4-diazabicyclo[2.2.2]octane-bis(sulfur dioxide) adduct as a sulfonyl source and KHF as a desirable fluorine source via a radical sulfur dioxide insertion and fluorination strategy.

Aryl sulfonyl fluoride synthesis palladium-catalyzed fluorosulfonylation of aryl thianthrenium salts.

We developed an efficient palladium-catalyzed fluorosulfonylation reaction of aryl thianthrenium salts to smoothly prepare various aryl sulfonyl fluorides using cheap NaSO as a convenient sulfonyl source in combination with -fluorobenzenesulfonimide (NFSI) as an ideal fluorine source under mild reduction conditions. A one-pot synthesis of aryl sulfonyl fluorides starting from various arenes was established as well without the need for separating aryl thianthrenium salts. The practicality of this protocol was demonstrated by gram-scale synthesis, derivatization reactions, and excellent yields.
