Nitrosoarenes as Nitrogen Source for Generation of Sulfonamides with the Insertion of Sulfur Dioxide under
<scp>Metal‐Free</scp>
Conditions
<sup>†</sup>
A metal‐free reaction of nitrosoarenes, aryldiazonium tetrafluoroborates, and sulfur dioxide under mild conditions is developed, giving rise to sulfonamides in moderate to good yields. This transformation proceeds efficiently at room temperature in the presence of cyclohexa‐1,4‐diene with a broad reaction scope. Good functional group compatibility is observed, including cyano, halo, and ester. A plausible
