    Product Description:
    Diethyl (2-oxopropyl)phosphonate, also known as diethyl acetonylphosphonate, is an organophosphorus compound with the molecular formula C7H15O4P and a molecular weight of 194.17 g/mol. It features a phosphonate ester group directly attached to a 2-oxopropyl (acetonyl) moiety, making it a versatile synthetic building block. This compound is primarily utilized in organic synthesis as a key reagent for the Horner-Wadsworth-Emmons (HWE) reaction. The presence of the phosphonate group adjacent to the carbonyl allows it to act as a stabilized carbanion precursor, enabling the formation of ж┴,ж┬-unsaturated ketones via olefination of aldehydes and ketones. It is also employed in the synthesis of phosphonate-containing pharmaceuticals, agrochemicals, and natural product analogs, where the phosphonate group can serve as a bioisostere for phosphate esters. As a stable and reactive intermediate, it is widely used in research laboratories for constructing carbon-carbon double bonds and introducing phosphorus functionality into complex molecules. Its handling requires standard precautions for organophosphorus compounds, including use in a fume hood and avoidance of skin contact.
