from the results observed with strained and sterically hindered syn 1,2-diols, which undergo oxidative cleavage via a 12-I-5 spirobicyclic periodinane. The use of TFA, a protonating solvent, promotes the formation of the 12-I-5 intermediate for 1,2-diols of all types (sec,sec, sec,tert and tert,tert), leading to efficient oxidative fragmentation.
IBX表现出与DMP相似的反应性这一事实由应变和空间受阻的syn 1,2-二醇(通过12-I-5螺双环高碘烷进行氧化裂解)观察到的结果证明。使用TFA(质子化溶剂)促进所有类型(仲,仲,仲,叔,叔和叔)的1,2-二醇的12-I-5中间体的形成,从而导致有效的氧化裂解。
