Aryliodonium imides

Preparation Aryliodonium imides 463 are usually prepared by the reaction of (diace-toxyiodo)arenes with the respective amides under basic conditions (Scheme 2.133) [623]. Most iodonium imides are relatively unstable at room temperature and their storage under an inert atmosphere at low temperature is recommended. Exothermic decomposition frequently occurs at the melting point of ylides and some of them were even claimed to be explosive [623].
