Ortho-phosphite ( PO 3 3 - ) : Mechanochemical Synthesis of a Missing Oxoanion and Precursor to Value-Added Organophosphorus Compounds.

ABSTRACT: Despite the ubiquity of the well-known phosphorus polyanion phosphite (HPO32-) , it appears to be the case that no simple salt of the corresponding conjugate base (PO33- , "ortho-phosphite") has ever been reported. We report the synthesis and characterization of this elusive species as a major component of a mixture obtained upon mechanochemical reduction of condensed phosphates, as evidenced by solid-state ³¹P NMR and Raman spectroscopy as well as subsequent reactivity studies. To corroborate the ³¹P NMR spectroscopic assignment, we independently generated Na₃PO₃ and K₃PO₃ by deprotonation of Na₂HPO₃ with NaCH₂SiMe₃ and of K₂HPO₃ with KCH₂Ph, respe
