Phosphite



  The phosphite ion (PO33−) is a organophosphorus compound with the formula P(OR)3.

Phosphorous acid

The phosphorus trichloride.

PBr3 + 3 ROH → 3 RBr + HP(O)(OH)2

PBr3 + 3 HP(O)(OH)2

PCl3 + 3 H2O → HCl

Synthesis of phosphite compounds

amine.

PCl3 + 3 ROH + 3 R'3N → P(OR)3 + 3R'3NHCl

Acid phosphites are compounds which contain a metal cation and a possible dihydrogen phosphite anion. These compounds are formed by reacting phosphorous acid with a metal carbonate (typically Rb, Cs, or Tl). Acid phosphites have crystalline structures consisting of alternating layers of HPO3 tetrahedrons and metal cations.
