Physical Data: bp (1), 94–97 °C/10 mmHg; (2), 79–81 °C/8 mmHg; (3), 70–72 °C/2 mmHg; (4) 100 °C/11 mmHg. Preparative Methods: acetalization of the 5-halo-2-pentanone (made by opening 2-acetylbutyrolactone with HX).1 5-Chloro-2-pentanone is commercially available, and has been converted to 5-iodo-2-pentanone by treatment with sodium iodide/acetone.1g,2 Alternatively, (2) is treated with sodium bromide/ethyl bromide to give (1);3a (1) or (2) may be treated with sodium iodide to give (3).3b–d Purification: vacuum distillation from a trace of sodium bicarbonate. Handling, Storage, and Precautions: store at ≤0 °C; use in a fume hood." @default.
