The review is devoted to one of the most substantial trends in the chemistry of hypervalent iodine – synthesis, structure, and properties of heterocyclic and pseudoheterocyclic systems based on λ³- and λ⁵-iodanes. Among the variety of cyclic reagents based on hypervalent iodine, special attention has recently been paid to iodanes having close contact between I and N atoms. The review is addressing the synthetic approaches, structural features, and application of these reagents. The review includes more than 100 literature sources, mainly covering publications from 1990 to 2020 and key research from earlier years.

N-杂环结构中的高价碘：合成，结构及其在有机合成中的应用

该审查致力于在高价碘的化学性质的最实质性的趋势之一-基于λ的合成，结构，和杂环和pseudoheterocyclic系统的性能³ -和λ ⁵ -iodanes。在基于高价碘的多种环状试剂中，最近特别关注在I和N原子之间紧密接触的碘。审查是针对这些试剂的合成方法，结构特征和应用。该综述包括100多种文献资料，主要涵盖1990年至2020年的出版物以及早期的关键研究。
