文摘

An improved method for the synthesis of cyclic low oxidation state P cations is presented. The only byproducts ofthe reaction of phosphorus triiodide with chelating phosphines are readily removed, resulting in an easily accessibleP^I reagent with an anion that can be readily replaced through salt metathesis chemistry. These P^I salts are surprisinglystable, even in O₂ and moisture, and the origin of this unusual stability is elucidated using density functional theorycalculations.
