AI Article Synopsis

  • Phosphorus heterocycles offer unique properties that carbon-based materials can’t match, thanks to phosphorus’s distinctive hybridization and electron-accepting qualities.
  • A new synthetic method has been developed for creating fused six-membered phosphorus heterocycles, particularly novel phosphaphenalenes.
  • These new compounds combine the advantages of five- and six-membered heterocycles and allow for various postfunctionalization reactions, expanding possibilities in conjugated materials.

Article Abstract

Phosphorus-based heterocycles provide access to materials with properties that are inaccessible from all-carbon architectures. The unique hybridization of phosphorus gives rise to electron-accepting capacities, a large variety of coordination reactions, and the possibility of controlling the electronic properties through phosphorus postfunctionalization. Herein, we describe a new noncatalyzed synthetic protocol to prepare fused six-membered phosphorus heterocycles. In particular, we report the synthesis of novel phosphaphenalenes. These fused systems exhibit the benefits of both five- and six-membered phosphorus heterocycles and enable a series of versatile postfunctionalization reactions. This work thus opens up new horizons in the field of conjugated materials.

Article Synopsis
  • Heterocycles containing phosphorus and nitrogen are increasingly used in various applications like luminescent materials and coordination chemistry, but seven-membered variants are under-researched.
  • The synthesis of 1,2,5-diazaphosphepines from azophosphines involves a detailed investigation of a stepwise mechanism leading to the formation of five-membered rings before expanding to the seven-membered structure.
  • The regioselective synthesis is facilitated by asymmetric alkynes, with borane B(CF) either catalyzing seven-membered ring formation or trapping an intermediate through a frustrated Lewis pair mechanism.

Positively charged phosphorus-containing heterocycles are characteristic core skeletons for functional molecules. While various phosphonium-containing five- or six-membered-ring compounds have been reported, the seven-membered-ring phosphepinium have not been fully studied yet. In this study, dithieno[3,2-b; 2',3'-f]phosphepinium ions containing electron-donating aminophenyl groups were synthesized.

Cyclotriphosphazene (CP) is a cyclic inorganic compound with the chemical formula NP. This unique molecule consists of a six-membered ring composed of alternating nitrogen and phosphorus atoms, each bonded to two chlorine atoms. CP exhibits remarkable versatility and significance in the realm of materials chemistry due to its easy functionalization via facile nucleophilic substitution reactions in mild conditions as well as intriguing properties of resultant final CP-based molecules or polymers.

Treatment of mixed phosphonium-iodonium ylides featuring a six-membered phenoxaphosphonium fragment with aqueous tetrafluoroboronic acid induces a rearrangement, resulting in expansion of the phosphacycle and oxidation of the phosphorus atom. The target difficult-to-access dibenzo[,][1,4]oxaphosphepine oxides (3 examples) were isolated in excellent yields (up to 95%) as mixtures of stereoisomers. Hydrolysis of a five-membered mixed ylide, a dibenzophosphole derivative, predominantly preserves the phosphole system with cycle expansion occurring as a side process.

Article Synopsis
  • * Researchers synthesized two new polycyclic organophosphorus heterocycles using Staudinger-type reactions involving specific phosphine and azidophenol compounds.
  • * The resulting compounds, B-B-TAP-OAP and B-B-AP-OAP, are stable in both air and a diluted aqueous solution, with computational studies suggesting that nitrogen gas formation and strong Si-F bond creation are crucial for their synthesis.
