fosforirungon

Fosforirungon is a synthetic phosphorous-containing compound first reported in the early 21st century by a team of chemists at the Instituto de Química Aplicada in São Paulo. The substance is obtained through a multi-step reaction that begins with the condensation of phosphoric acid and 2-azidoethanol, followed by a photochemical rearrangement in the presence of a platinum catalyst. The resulting molecule contains a phosphorous atom bonded to a guanidinium-like scaffold, conferring distinctive electron‑rich properties that differ from conventional phosphoramides. Early spectroscopic analyses indicate that fosforirungon possesses a highly diffuse charge distribution, providing it with a moderate basicity (pKb ≈ 8.6) and the ability to act as an organophosphorus ligand in transition‑metal complexes.

The most prominent use of fosforirungon identified to date is as a precursor in the synthesis of polymeric materials with improved flame‑retardant characteristics. In polymer chemistry laboratories, fosforirungon has been incorporated into polycarbonate matrices via copolymerization with bisphenol‑A diglycidyl ether. The resulting composites exhibit a higher resistance to hydrolysis and a lower coefficient of thermal expansion relative to unmodified polycarbonate. Additionally, preliminary studies suggest that fosforirungon may serve as a stabilizer in the production of biodegradable plastics, although comprehensive biodegradability assays are pending.

Because fosforirungon is a relatively new entrant to the chemical literature, safety data are limited. Initial handling guidelines recommend that the compound be stored in a cool, dry place and that gloves and eye protection be used during synthesis. No large‑scale industrial production processes have yet been disclosed, and most research on fosforirungon remains within academic laboratories. Further investigation is needed to fully understand its potential environmental impact and long‑term stability.
