• Chlorine (Cl₂) reacts with sodium hydroxide to sodium chloride, sodium chlorate and water. One atom of chlorine gets reduced to a chlorine anion with oxidation number -1. The other chlorine atom gets oxidized to a oxidation number of +5 to the chlorate ion.
• In the Cannizzaro reaction an aldehyde is converted into an alcohol and a carboxylic acid. In the related Tishchenko reaction the organic redox reaction product is the corresponding ester.

Disproportionation is the opposite of synproportionation.
