実験手順
To a mixture of 1,3-dioxan (3 ml, 0.035 mmol) and acetic anhydride (3.3 ml, 0.035 mmol) at 0° C., was added a drop of concentrated sulphuric acid. The mixture was then stirred for 14 h at 20° C., added with sodium acetate (2 g) and filtrated. The residue, distilled in vacuo (120° C., 16 mmHg), gave 1-acetoxy-3-acetoxymethoxypropane (3.34 g, 50%) as a colorless oil.
