Application

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.
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.

Chlorotrimethylsilane completely dealkylates phosphonate esters at elevated temperature in a sealed reaction vessel. These conditions are tolerated by a variety of functional groups and lead to high conversions of dimethyl, diethyl and diisopropyl phosphonates to their corresponding phosphonic acids.

Single-walled carbon nanotube (SWNT) networks were used to detect hazardous dimethyl-methyl-phosphonate (DMMP) gas in real time, employing two different metals as electrodes. Random networks of SWNTs were simply obtained by drop-casting a SWNT-containing solution onto a surface-oxidized Si substrate. Although
