Application
Dimethyl phosphite may be used as an effective alternative to organic tin hydrides as radical reducing agents for organic halides, thionoesters, and isocyanides to form the corresponding hydrocarbons. Radical translocation/cyclization reactions of terminal alkynes to form cyclic phosphonates can also be effectively carried using dimethyl phosphite as a reagent under tin-free condition.
Dimethyl phosphite is used in the synthesis of α-aminophosphonates, which are medicinally important phosphorus analogs of amino acids, by treating with an amine and an aldehyde or a ketone. It can also be employed in asymmetric hydrophosphonylation of aldehydes to synthesize optically active α-hydroxy phosphonates.
