hypervalent iodine compounds were prepared by the reaction of saccharine with (diacetoxyiodo)arenes or acetoxybenziodoxole. Structures of these new imidoiodanes were established by X‐ray crystallography. The saccharin‐based μ‐oxo‐bridged imidoiodane readily reacts with silyl enol ethers under mild conditions to give the corresponding α‐aminated carbonyl compounds in moderate yields.
