This Minireview outlines the synthesis and reactivity of homoleptic, cyclic oligophosphanes, which have been known for more than 150 years. We will discuss a variety of (PR)_n (n = 3,4,5,6) species and outline approaches towards their syntheses in the first part of this review. Then the unique reactivity of these inorganic ring systems will be discussed in detail with a focus on recent findings within the last 20 years. First ring expansion reactions will be described, which are mainly restricted to cyclotriphosphanes. Secondly, ring fragmentation will be highlighted, including phosphinidene transfer reactions. Furthermore, cyclooligophosphanes can be functionalized while retaining the parent ring structures. As oligophosphanes offer multiple donor sites, in a last part the coordination chemistry of these species is highlighted. We hope that this Minireview will spark further interest in this underexplored class of compounds as reagents in inorganic and organic synthesis, as well as the design of new P‐containing materials.

单环同质寡膦的合成与反应性

这份Minireview概述了均化的环状低聚膦酸酯的合成和反应性，众所周知，它们已有150多年的历史了。我们将讨论各种（PR）_n（n= 3,4,5,6）种，并在本综述的第一部分概述了它们的合成方法。然后将详细讨论这些无机环系统的独特反应性，重点是过去20年中的最新发现。将描述第一环扩环反应，其主要限于环三膦。其次，将突出环断裂，包括次膦基转移反应。此外，可以在保留母体环结构的同时官能化环寡膦。由于低磷烷具有多个供体位点，因此最后一部分着重介绍了这些物种的配位化学。我们希望这份Minireview能够引起人们对这种尚未开发的化合物作为无机和有机合成试剂的兴趣，
