Versuchsvorschrift

A solution of furan (1 mmole) in diethyl ether was treated with TMEDA (N,N,N′N′-tetramethylethylenediamine) (1 mmole) and nBuLi (2 mmole) at −78° C. for 0.5 h. Diethyl chlorophosphate (1.2 mmole) was added to the reaction mixture and stirred for another hour. Extraction and distillation gave diethyl 2-furanphosphonate as a clear oil.
