Several experiments with the compound resulted in a series of fires and explosions. Some of the compounds that produced violent reactions with O 2 F 2 include ethyl alcohol, methane, ammonia, and even water ice. [10] With BF 3 and PF 5, it gives the corresponding dioxygenyl salts: [1] [11] 2 O 2 F 2 + 2 PF 5 → 2 [O 2] + [PF 6] − + F 2
Oxygen difluoride reacts with water to form hydrofluoric acid: OF 2 + H 2 O → 2 HF + O 2. It can oxidize sulphur dioxide to sulfur trioxide and elemental fluorine: OF 2 + SO 2 → SO 3 + F 2. However, in the presence of UV radiation, the products are sulfuryl fluoride (SO 2 F 2) and pyrosulfuryl fluoride (S 2 O 5 F 2): OF 2 + 2 SO 2 → S 2 O ...
Magnesium has a mild reaction with cold water. The reaction is short-lived because the magnesium hydroxide layer formed on the magnesium is almost insoluble in water and prevents further reaction. Mg(s) + 2H 2 O(l) Mg(OH) 2 (s) + H 2 (g) [11] A metal reacting with cold water will produce a metal hydroxide and hydrogen gas.
Like the other oxygen fluorides, O 3 F 2 is endothermic and decomposes at about 115 K with the evolution of heat, which is given by the following reaction: 2 O 3 F 2 → O 2 + 2 O 2 F 2. O 3 F 2 is safer to work with than ozone, and can be evaporated, or thermally decomposed, or exposed to electric sparks, without any explosions. But on contact ...
Of the two half reactions, the oxidation step is the most demanding because it requires the coupling of 4 electron and proton transfers and the formation of an oxygen-oxygen bond. This process occurs naturally in plants photosystem II to provide protons and electrons for the photosynthesis process and release oxygen to the atmosphere, [ 1 ] as ...
Diphosphorus tetrafluoride reacts with oxygen or water to yield diphosphorus tetrafluoride oxide, which has one oxygen atom inserted between the two phosphorus atoms: [2] [7] 2 P 2 F 4 + H 2 O → 2 PHF 2 + F 2 POPF 2. The latter compound is a gas with boiling point around −18 °C.

For small scale reactions, SF 4 can be inconvenient since it is a gas and stainless steel reaction vessels are required. Many transformations require elevated temperatures. The reaction generates hydrogen fluoride. These concerns have led to interest in alternative fluorinating reagents. [1]
