6-trimethoxyphenyl)iodonium trifluoroacetate salts from aryl iodides is described. Stoichiometric quantities of trifluoroacetic acid and trimethoxybenzene are used as the counteranion and auxiliary precursors, respectively, under oxidizing conditions. The reaction occurs at mild temperature, is broad in scope, and does not require a separate anion exchange step to install the trifluoroacetate group. The intermediacy
描述了由芳基碘化物直接合成芳基(2,4,6-三甲氧基苯基)碘鎓三氟乙酸盐。在氧化条件下,化学计量的三氟乙酸和三甲氧基苯分别用作抗衡阴离子和辅助前体。该反应在温和的温度下发生,范围广,并且不需要单独的阴离子交换步骤来安装三氟乙酸酯基团。两个不同的双羧基芳基λ的中间性3 -iodanes在机构假设。
