Saccharin-based µ-oxo imidoiodane: a readily available and highly reactive reagent for electrophilic amination.

Three new saccharin-based 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.
