Synthesis
editThe salt theoretically results from the neutralization of hypofluorous acid (HOF) and lithium hydroxide (LiOH). It can be formed by the action of fluorine on lithium hydroxide:
- 6 F2 + 6 LiOH → 2 LiF + O2 + 4 LiOF + 6 HF
Chemical properties
editThe compound is quite unstable, since it contains oxygen in the oxidation state of 0. It, therefore, tends to decompose to lithium fluoride and oxygen gas:
- 2 LiOF → 2 LiF + O2
