New powerful hypervalent iodine(V) oxidants, tosylate and mesylate derivatives of 2-iodoxybenzoic acid (IBX), were prepared by the reaction of IBX with the corresponding sulfonic acids. Single crystal X-ray crystallography of the diacetate derivative of IBX-tosylate revealed an unusual heptacoordinated iodine geometry without any significant intermolecular secondary interactions.
通过IBX与相应的磺酸反应,制得了新的强效高价碘(V)氧化剂,即2-碘氧基苯甲酸(IBX)的甲苯磺酸酯和甲磺酸酯衍生物。IBX-甲苯磺酸酯的二乙酸酯衍生物的单晶X射线晶体学分析显示异常的七配位碘几何结构,没有任何明显的分子间二级相互作用。
