Anwendungen

Diethyl 2,2-diethoxyethylphosphonate is used reactant for synthesis of α,β-alkenal derivatives by two-carbon homologation, lower rim-phosphonylated rexorcinol calix[4]arenes by condensation reactions, α-Phosphovinyl radicals via a radical trapping sequence, inhibitors of reverse transcriptase via 1,3-dipolar cycloadditions and for Friedel-Crafts reactions.

Bemerkungen

Keep container tightly sealed. It is hygroscopic in nature. It is sensitive to moisture. Store under dry inert gas. Protect from humidity and water.
