Hypervalent iodine compounds with two I–N bonds, containing 5-substituted tetrazoles as the ligands PhI(N4CR)2 (R = CH3, C6H5, and 4-CH3C6H4), were synthesized from PhI(O2CCF3)2 or PhICl2 and the corresponding tetrazole potassium salts. Alternatively, PhIO was reacted with the free tetrazoles, and the reactions afforded either PhI(N4CR)2 or, in most cases, μ-oxo- or oligomeric compounds with several I and O atoms in the backbone and two terminal tetrazole groups. The isolated compounds were reasonably stable in the solid state as well as in solution at room temperature but explosive at elevated temperatures (135–180 °C depending on the structure). The crystal structure of one representative compound (an oligomer with three I atoms in the backbone and 5-phenyltetrazole end groups) was solved and refined from synchrotron powder X-ray diffraction. The novel compounds were characterized by cyclic voltammetry and were found to be strong oxidants. In addition, they proved to be useful reagents for the iodotetrazolylation of unsaturated compounds such as styrene and cyclohexene and for the transfer of tetrazole groups to N,N-dimethylaniline.

高价碘化合物与四唑配体
由以下化合物合成具有两个I–N键的高价碘化合物，它们含有5个取代的四唑作为配体PhI（N 4 CR）2（R = CH 3，C 6 H 5和4-CH 3 C 6 H 4）。 PhI（O 2 CCF 3）2或PhICl 2和相应的四唑钾盐。或者，使PhIO与游离的四唑反应，并得到PhI（N 4 CR）2。或者，在大多数情况下，是在骨架上带有几个I和O原子且带有两个末端四唑基的μ-氧代或低聚化合物。分离出的化合物在室温下在固态和溶液中都相当稳定，但在高温下（135-180°C，取决于结构）会爆炸。通过同步加速器粉末X射线衍射分析并精制了一种代表性化合物（在主链上具有3个I原子且具有5-苯基四唑端基的低聚物）的晶体结构。通过循环伏安法表征了这些新型化合物，发现它们是强氧化剂。此外，它们被证明是用于不饱和化合物（如苯乙烯和环己烯）的碘四唑基化以及将四唑基团转移至N，N的有用试剂。-二甲基苯胺。
