N-Hydroxyphthalimide and N-hydroxysuccinimide have been arylated with diaryliodonium salts to provide N-aryloxyimides in excellent yields in short reaction times. A mild and hydrazine-free hydrolysis gives aryloxyamines, which are valuable building blocks in the synthesis of oxime ethers and benzofurans.
