Abstract: | 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 [Eurn:x-wiley:14337851:media:anie201702558:anie201702558-math-0001 (Surn:x-wiley:14337851:media:anie201702558:anie201702558-math-0002 )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. |
