Reaction Steps

A solution of phenylacetylene (1 mmole) in anhydrous THF (5 mL) was treated with TMEDA (1.2 mmole) followed by n-BuLi (1.2 mmole) at −78° C. After 30 min the reaction was treated with diethyl chlorophosphate, and the resulting solution was stirred at −78° C. for 1 h. The reaction was quenched with saturated ammonium chloride. Extraction and chromatography gave 1-diethylphosphono-2-phenylacetylene as an oil.
