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 ...
Water-reactive substances [1] are those that spontaneously undergo a chemical reaction with water, often noted as generating flammable gas. [2] Some are highly reducing in nature. [ 3 ] Notable examples include alkali metals , lithium through caesium , and alkaline earth metals , magnesium through barium .
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 ...
The reaction may otherwise involve the functional groups of the molecule, and is a versatile class of reactions that can occur in acidic or basic conditions or in the presence of a catalyst. This class of reactions is a vital part of life as it is essential to the formation of peptide bonds between amino acids and to the biosynthesis of fatty ...
The reaction of F 2 with organic compounds is, however, highly exothermic and can lead to non-selective fluorinations and C–C cleavage, as well as explosions. [6] Only a few selective radical fluorination methods have been reported. [7] [8] The use of fluorine for radical fluorination is mainly limited to perfluorination reactions. [5]
Water splitting can be done at higher pH values as well however the standard potentials will vary according to the Nernst equation and therefore shift by -59 mV for each pH unit increase. However, the total cell potential (difference between oxidation and reduction half cell potentials) will remain 1.23 V.

Water oxidation is catalyzed by a manganese-containing enzyme complex known as the oxygen evolving complex (OEC) or water-splitting complex found associated with the lumenal side of thylakoid membranes. Manganese is an important cofactor, and calcium and chloride are also required for the reaction to occur. [4]
