FormLiquid

Triethyl phosphonoacetate serves as a reactant used in Horner-Wadsworth-Emmons reactions, Tsuji-Trost type reactions, Intramolecular Heck-type cyclization and isomerizations and Intramolecular aryne-ene reactions. In Horner-Wadsworth-Emmons reaction, it is utilized as a reagent to prepare chiral 2-methylcyclopropanecarboxylic acid from (S)-propylene oxide.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Wadsworth-Emmons (Horner) reaction with aldehydes and ketones gives acrylic esters. See, e.g.: Org. Synth. Coll., 5, 509, 547 (1973), and Appendix 1.
Base-catalyzed aldol, Cannizzaro and saponification reactions can be minimized, by the use of, e.g.: K₂CO₃: Synthesis, 300 (1983); Tetrahedron Lett., 26, 53 (1985); F^-: Tetrahedron Lett., 21, 2161 (1980); N-ethyldiisopropylamine + LiCl: Tetrahedron Lett., 25, 2183 (1984); Et₃N + Li halides: J.

Reaction with aqueous formaldehyde does not lead to the expected Wadsworth-Emmons product, but to ethyl ɑ-(hydroxymethyl)acrylate, a precursor of the synthetically useful ethyl ɑ-bromomethylacrylate, by condensation with the initially-formed aldol product: Org. Synth. Coll., 8, 265 (1993).
