twisting-promoted rate enhancement. Furthermore, the reagent is efficient for selective oxidation of sulfides to sulfoxides, a transformation that otherwise occurs only sluggishly with standard IBX. The facile synthetic accessibility and its mild as well as non-hazardous nature render Me-IBX a stable equivalent of Dess–Martin periodinane reagent in organic oxidations.
邻位甲基取代的Me-IBX是IBX的第一个修饰类似物,由于两种因素的综合作用,即在低溶解度和高价扭曲促进速率的提高,该化合物在室温下可氧化普通有机溶剂中的醇。此外,该试剂对于将硫化物选择性氧化为亚砜是有效的,否则这种转化只能在标准IBX的情况下缓慢进行。容易获得的合成方法及其温和以及无害的性质使Me-IBX在有机氧化反应中稳定地相当于Dess-Martin高碘烷试剂。
