実験手順
A solution of diethyl (benzylthiomethyl)phosphonate (10 g., 0.036 mole) in 75 ml. of methylene chloride was, with ice-bath cooling, treated with 7.29 g. (0.036 mole) of m-chloroperoxybenzoic acid portionwise. After the addition was complete, the mixture was stirred for 1 hour at ambient temperature, filtered to remove precipitate, and the filtrate concentrated in vacuo. The residue was chromatographed on silica gel by eluting the column with ethyl acetate which gave 5.9 g. of the title compound.
