Inorganic macrocycles, based on non-carbon backbones, present exciting synthetic challenges in the systematic assembly of inorganic molecules, as well as new avenues in host–guest and supramolecular chemistry. Here we demonstrate a new high-yielding modular approach to a broad range of trimeric and hexameric S- and Se-bridged inorganic macrocycles based on cyclophosphazane frameworks, using the building blocks [S=(H)P(μ-NR)]2. The method involves the in situ generation of the key intermediate [E
(S
)P(μ-NR)]22−(E=S, Se) dianion, which can be reacted with electrophilic [ClP(μ-NR)]2 to give PIII/PV hexameric rings or reacted with I2 to give trimeric PV variants. Important issues which are highlighted in this work are the competitive bridging ability of S versus Se in these systems and the synthesis of the first air-stable and chiral inorganic macrocycles.

无机膦环大环化合物的模块化方法
基于非碳主链的无机大环化合物在无机分子的系统组装中提出了令人振奋的合成挑战，并且在宿主-客体和超分子化学中开辟了新途径。在这里，我们使用结构单元[S =（H）P（μ-NR）] 2展示了一种新的高产模块化方法，该方法基于环磷氮烷骨架，可广泛应用于三聚和六聚S和Se桥联的无机大环化合物。该方法涉及原位生成关键中间体[E
（S
）P（μ-NR）] 2 2-（E = S，Se）的二价阴离子，它可以与亲电[ClP（μ-NR）] 2反应生成P III / P V六聚环或与I 2反应给出三聚体P V变体。这项工作中强调的重要问题是在这些系统中S与Se的竞争桥连能力以及第一个空气稳定和手性无机大环化合物的合成。
