The IUPAC Nomenclature for Transformations is a
methodology for naming a
chemical reaction. Traditionally a chemical reaction especially in
organic chemistry is named after its inventor, the so-called
name reaction, to name just a few:
Knoevenagel condensation
In organic chemistry, the Knoevenagel condensation () reaction is a type of chemical reaction named after German chemist Emil Knoevenagel. It is a modification of the aldol condensation.
A Knoevenagel condensation is a nucleophilic addition of ...
,
Wittig reaction or
Diels-Alder reaction. A lot of reactions derive their name from the reagent involved like
bromination or
acylation. On rare occasions, the reaction is named after the company responsible like in the
Wacker process
The Wacker process or the Hoechst-Wacker process (named after the chemical companies of the same name) refers to the oxidation of ethylene to acetaldehyde in the presence of palladium(II) chloride as the catalyst. This chemical reaction was one of ...
or the name only hints at the process involved like in the
halogen dance rearrangement The halogen dance rearrangement is an organic reaction in which a halogen substituent moves to a new position on an aromatic ring system. The reaction belongs to a class of organic reactions called 1,2-rearrangements. The original halogen dance i ...

IUPAC nomenclature is designed for naming organic compounds themselves.
The IUPAC Nomenclature for Transformations was developed in 1981 and presents a clear-cut methodology for naming an organic reaction. It incorporates the reactant and product in a
chemical transformation
A chemical substance is a form of matter having constant chemical composition and characteristic properties. Some references add that chemical substance cannot be separated into its constituent elements by physical separation methods, i.e., wi ...
together with one of three transformation types:
*
substitutions have the infix ''-de-'' example: methoxy-de-bromination for the chemical reaction of a bromo-alkane to an alkoxy-alkane
*
additions end with ''-addition'' example: hydro-bromo-addition for the hydrobromination of an alkene
*
eliminations. end with ''-elimination'' example: dibromo-elimination.
