Versuchsvorschrift

Tris(trimethylsilyl) phosphite (2 molar equiv.) in an appropriate dry solvent was added dropwise to a stirred solution of acetyl chloride (1 molar equiv.) in an appropriate dry solvent at room temperature and the mixture stirred for 10 minutes. Excess methanol was then added and the mixture stirred for 5 minutes to decompose the silyl esters. The volatile components in the reaction mixture were then removed under reduced pressure to leave the title compound in good purity.
