Description Application Diethyl vinylphosphonate (DEVP) can be used as a precursor for the synthesis of: • α, β-unsaturated phosphonates by reacting with arylboronic acids via Pd-catalyzed Mizoroki−Heck reaction. • 2-(arylamino)ethyl phosphonates by condensing with primary and secondary amines via the aza-Michael addition reaction. It can be also employed as a monomer unit for the preparation of high-molecular-weight polymer, poly(diethyl vinylphosphonate) using lanthanide complexes.{18) Diethyl vinylphosphonate has been used in the preparation of diethyl N-alkyl-2-aminoethylphosphonate.
