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.
通过糖精与(二乙酰氧基碘)芳烃或乙酰氧基苯并d唑的反应制备了三种基于糖精的高价碘化合物。这些新的亚氨基碘的结构是通过X射线晶体学确定的。基于糖精的μ-氧代桥接亚碘碘在温和的条件下易于与甲硅烷基烯醇醚反应,以中等收率得到相应的α-胺化羰基化合物。
