thermal decomposition to MeF and
CO2 | [storage]
As with all hypofluorites this reagent should be treated with care.
When not in solution, or when very concentrated, it may explode. Solutions of up to 0.3 M in CFCl3 at -
78 °C or in MeCN at -45 °C are stable for days, but at rt the half-life is around 2-4 h. No data about the
toxicity are available, but some hypofluorite derivatives such as CF3OF and F2O are known to be toxic. Use
in a fume hood. | [Purification Methods]
AcOF oxidizes iodides to iodine which is then titrated (AcOF + 2KI + H+ -
> KF + AcOH + K+ + I2). |
