실험 절차

A solution of 2-thienyllithium in THF (1 mmol) was added to a solution of diethyl chlorophosphate (1 mmol) at −78° C. under nitrogen. After 2 h the reaction was warmed to room temperature and quenched with brine. Extraction and chromatography afforded 2-diethylphosphonothiophene as a yellow oil. TLC: Rf=0.37, 50% EtOAc—hexane.
