Johan Gadolin studied one such reaction of tin and tartrates, while another is the catalase-assisted breakdown of hydrogen peroxide into water and diatomic oxygen.
One example of this occurs in the de Meijere modification of the Kulinkovich reaction. Another example of it is the formation of an ester from two aldehydes occurs in the Tishchenko reaction. The Kornblum-DeLaMare rearrangement is one since peroxide is converted to a ketone and an alcohol, and another example is the Cannizzaro reaction. Johan Gadolin studied one such reaction of tin and tartrates, while another is the catalase-assisted breakdown of hydrogen peroxide into water and diatomic oxygen. A simple example is the formation of bleach from lye and diatomic chlorine. The opposite of comproportionation is, FTP, what type of reaction that forms two species, usually one reduced and the other oxidized, from a single original.
