Triethyl phosphite → Diethyl ((phenylthio)methyl)phosphonate

Participants

Reaction Steps

A stirred solution of 40.0 grams (0.25 mole) of phenylthiomethyl chloride and 58.2 grams (0.35 mole) of triethylphosphite was heated at 150°-160° C. for 4 hours, cooled and excess triethylphosphite removed by evaporation under reduced pressure. The residue was purified by distillation to give 61.1 grams (93.1%) of diethyl phenylthiomethylphosphonate; b.p. 155° C./0.6 mm. The nmr and the ir spectra were consistent with the assigned structure.
