IUPAC Nomenclature for Transformations
Encyclopedia
The IUPAC Nomenclature for Transformations is a methodology for naming a chemical reaction
Chemical reaction
A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. Chemical reactions can be either spontaneous, requiring no input of energy, or non-spontaneous, typically following the input of some type of energy, such as heat, light or electricity...

. Traditionally a chemical reaction especially in organic chemistry
Organic chemistry
Organic chemistry is a subdiscipline within chemistry involving the scientific study of the structure, properties, composition, reactions, and preparation of carbon-based compounds, hydrocarbons, and their derivatives...

 is named after its inventor, the so called named reaction, to name just a few: Knoevenagel condensation
Knoevenagel condensation
The Knoevenagel condensation reaction is an organic reaction named after Emil Knoevenagel. It is a modification of the Aldol condensation.A Knoevenagel condensation is a nucleophilic addition of an active hydrogen compound to a carbonyl group followed by a dehydration reaction in which a molecule...

, Wittig reaction
Wittig reaction
The Wittig reaction is a chemical reaction of an aldehyde or ketone with a triphenyl phosphonium ylide to give an alkene and triphenylphosphine oxide....

 or Diels-Alder reaction
Diels-Alder reaction
The Diels–Alder reaction is an organic chemical reaction between a conjugated diene and a substituted alkene, commonly termed the dienophile, to form a substituted cyclohexene system. The reaction can proceed even if some of the atoms in the newly formed ring are not carbon...

. A lot of reactions derive their name from the reagent involved like bromination or acylation
Acylation
In chemistry, acylation is the process of adding an acyl group to a compound. The compound providing the acyl group is called the acylating agent....

. On rare occasions the reaction is named after the company responsible like in the Wacker process
Wacker process
The Wacker process or the Hoechst-Wacker process originally referred to the oxidation of ethylene to acetaldehyde by oxygen in water in the presence of a tetrachloropalladate catalyst...

 or the name only hints to the process involved like in the halogen dance rearrangement
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 is the base-catalysed rearrangement of...

.The related IUPAC nomenclature
IUPAC nomenclature
A chemical nomenclature is a set of rules to generate systematic names for chemical compounds. The nomenclature used most frequently worldwide is the one created and developed by the International Union of Pure and Applied Chemistry ....

 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
Chemical transformation
In chemistry a chemical transformation shows the conversion of a substrate to a product omitting the reagents and catalysts or underlying reaction mechanism as opposed to a chemical reaction...

 together with one of three transformation types:
  • substitutions
    Substitution reaction
    In a substitution reaction, a functional group in a particular chemical compound is replaced by another group. In organic chemistry, the electrophilic and nucleophilic substitution reactions are of prime importance...

     have the infix -de- example: methoxy-de-bromination for the chemical reaction of a bromo-alkane to an alkoxy-alkane
  • additions
    Addition reaction
    An addition reaction, in organic chemistry, is in its simplest terms an organic reaction where two or more molecules combine to form a larger one....

     end with -addition example: hydro-bromo-addition for the hydrobromination of an alkene
  • eliminations
    Elimination reaction
    An elimination reaction is a type of organic reaction in which two substituents are removed from a molecule in either a one or two-step mechanism...

    . end with -elimination example: dibromo-elimination.
