Synthesis of <i>N</i>‑Bromo and <i>N</i>‑Iodo Imides: A Rapid Redox-Neutral and Bench Stable\nProcess

This report presents\na rapid, ecofriendly technique for the formation\nof commonly used <i>N</i>-bromo and <i>N</i>-iodinating\nreagents by reacting readily available <i>N</i>-chloro derivatives\nwith inorganic bromide and iodide salts. All reagents were easily\nhandled, commercially available, and bench stable. This strategy illustrates\nthe expeditious formation of these halogenating reagents in multigram\nscale in high-yields and purity with an operationally straightforward\nrecrystallization. The mechanistic details suggest an in situ generation\nof an interhalogen species.
