Phosphorous acid
Recent Literature
A new convenient and scalable synthesis of phenylacetic acids via iodide
catalyzed reduction of mandelic acids relies on in situ generation of hydroiodic
acid from catalytic sodium iodide, employing phosphorus acid as the
stoichiometric reductant.

Iodine mediates a reduction of phosphine oxides (sulfides) to phosphines
using phosphonic acid under solvent-free conditions. Both tertiary monophosphine
oxides and bis-phosphine oxides readily produce monodentate and bidentate
phosphines, respectively, in good yields and in case of (R)-(+)-2,2′-bis(diphenylphosphino)-1,1′-binaphthyl
dioxide without racemization.
