While the implication of the aromaticity concept has been dramatically expanded to date since its emergence in 1865, the classical [4n+2]/4n-electron counting protocol still plays an essential role in evaluating the aromatic nature of compounds. Over the last few decades, a variety of heavier heterocycles featuring the formal [4n+2] π-electron arrangements have been developed, which allows for assessing their aromatic nature. In this review, we present recent developments of the [4n+2]-electron systems of heavier heterocycles involving group 13–15 elements. The synthesis, spectroscopic data, structural parameters, computational data, and reactivity are introduced.

[4n+2]-电子系统的含重元素芳烃

尽管自 1865 年出现以来，芳香性概念的含义已显着扩展，但经典的 [4 n +2]/4 n -电子计数协议在评估化合物的芳香性方面仍然发挥着重要作用。在过去的几十年里，已经开发了各种具有正式 [4 n +2] π 电子排列的较重的杂环，这可以评估它们的芳香性。在这篇综述中，我们介绍了涉及 13-15 族元素的较重杂环的 [4 n +2]-电子系统的最新进展。介绍了合成、光谱数据、结构参数、计算数据和反应性。
