Correction to “Pd-Catalyzed Conversion of Aryl Iodides to Sulfonyl Fluorides Using SO₂ Surrogate DABSO and Selectfluor”

Abstract

The following text should be added as a third paragraph in the Experimental Section. The authors apologize for any inconvenience to the scientific community that this omission may have caused.Fluorination Step. After 14 h, the tube was allowed to cool to room temperature. The tube was opened to air, and Selectfluor (638 mg, 1.8 mmol, 2 equiv) was added followed by acetonitrile (3 mL). The Schlenk tube was resealed, and the mixture was allowed to stir at room temperature for 2 h. After 2 h, the solvents were removed by rotary evaporation. The crude product was isolated using automated flash chromatography (SiO 2 ) on a 100% hexane to 60:40 hexanes/ethyl acetate over 14 min unless otherwise noted.

DABSO as a SO2 gas surrogate in the synthesis of organic structures

“…26 or Selectfluor as a fluorine donor to synthesize similar products. 27,28 Sulfonyl fluoride is an important functional group found in some bioactive organic structures which are commonly used as covalent protein inhibitors and bioprobes. [29][30][31][32] Liu et al used arenediazonium salts 6 to react with DABSO and KHF 2 as an ideal fluorine source in the presence of a Cu (II) catalytic system for the preparation of sulfonyl fluorides 5 (Scheme 5).…”
