Ionic liquids-media for unique phosphorus chemistry

摘要

Ionic liquids have been shown to offer hitherto unseen control as both a storage solvent for PC1_3 and POC1_3 and reaction media for fluorination and mixed anhydride formation under benign conditions.Phosphorus trichloride(PCl_3)and phosphorus oxychloride(POCl_3)are major precursors for flame-retardant materials,pesticides,nerve gases and plasticizers,as well as key reagents in numerous synthetic conversions such as chlorination reactions and Vilsmeier-Hack formylations of aromatics.
