Descrizione

Descrizione generale

H₃PO_2, a monobasic oxyacid, is also referred to as phosphinic acid. H₃PO₂ participates as a reducing agent for the conversion of aromatic and aliphatic diselenides to the corresponding selenols.
It undergoes oxidation in the presence of Ce(IV) and a strong acid to afford cerium(IV) hypophosphite complex ions.
