| Triethyl phosphonoacetate Usage And Synthesis |
| Chemical Properties | Triethyl phosphonoacetate is Colorless to light yellow liqui
| | Uses | Triethyl phosphonoacetate is used for Horner-Emmons modification.
| | Uses | 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. | | Purification Methods | Purify it by fractional distillation, preferably in vacuo. NMR has P resonance at 19.5 relative to orthophosphate.
