Beschreibung

Anwendung

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.
