使用碘和高碘酸直接碘化以下带有大基团的多烷基苯，并以相当高的收率获得相应的单碘化产物：4-叔丁基-1, 2-二甲基苯、5-叔丁基-1, 3-二甲基苯、5-叔丁基-1, 2, 3-三甲基苯、1, 2, 4, 5-四异丙基苯和对二叔丁基苯。多甲基苯的多碘化反应也进展顺利，得到了高产率的多碘化合物。通过对各种直接方法的比较，证明上述试剂是多种多烷基苯的最佳碘化剂。
The following polyalkylbenzenes bearing bulky groups have been subjected to direct iodination using iodine and periodic acid, and the corresponding mono-iodinated products have been obtained in fairly high yields: 4-t-butyl-1, 2-dimethylbenzene, 5-t-butyl-1, 3-dimethylbenzene, 5-t-butyl-1, 2, 3-trimethylbenzene, 1, 2, 4, 5-tetraisopropylbenzene and p-di-t-butylbenzene. The polyiodination of polymethylbenzenes has also proceeded smoothly, giving polyiodo compounds in high yields. A comparison of various direct methods has proved the above reagent to be the best iodinating agent for a variety of polyalkylbenzenes.
