from NaIO 4 and either I 2 or KI in concentrated H 2 SO 4 (minimum 95% by weight). In general a small excess of the dark brown iodinating solution was used (1.1/1.5 equivalents, for nitrobenzene two equivalents was required). The iodinations were conducted at 25-30 °C with a reaction time of 1-2 hours using either a 'direct' or an 'inverse' method of aromatic iodination to give mono- or diiodinated pure
用强亲电 I + 试剂对失活的芳烃进行单碘化或二碘化,这些试剂由 NaIO 4 和 I 2 或 KI 在浓 H 2 SO 4 中制备(至少 95% 重量)。通常使用稍微过量的深棕色碘化溶液(1.1/1.5 当量,对于硝基苯需要两个当量)。碘化在 25-30 °C 下进行,反应时间为 1-2 小时,使用芳香族碘化的“直接”或“反向”方法以 31-91% 的优化产率得到单碘化或二碘化纯产物。

cholesteryl phenylalkanoic esters was synthesized in which the acyl moiety served as the carrier for radioiodine. Tissue distribution studies in rats revealed that several of these radioiodinated esters selectively accumulated in steroid-secreting tissues, such as the adrenal cortex and ovary. Furthermore, this selective uptake was shown to correlate with the stability of these esters to in vivo hydrolysis
