The syntheses and properties of long‐lived arsenic, antimony, and bismuth‐centered radicals are reviewed. In contrast to the rich phosphorus‐based radical chemistry, that of the heavier congeners is far less advanced, which can be attributed to the increased instability of coordinatively and electronically unsaturated heavy main‐group element centers. However, the development of new synthetic strategies and stabilization methods particularly in the last decade enabled the isolation and characterization of several unpaired electron‐containing heavy group 15 element species featuring various structural motifs and electronic properties. The long‐lived character of these radicals allowed for the elucidation of their electronic structures and bonding properties, as well as the exploration of their unique reactivity.

重元素15砷，锑和铋的长寿命自由基
审查了长寿命砷，锑和铋中心自由基的合成和性质。与富含磷的自由基化学相反，较重的同类化合物远没有那么先进，这可以归因于配位和电子不饱和重主族元素中心的不稳定性增加。但是，新合成策略和稳定化方法的发展，特别是在最近十年中，使得能够分离和表征几种具有不同结构基序和电子特性的未配对的含电子的重15族元素。这些自由基的长寿命特性使其能够阐明其电子结构和键合性质，并探索其独特的反应性。
