In chemical nomenclature, the IUPAC nomenclature of organic chemistry is a method of naming organic chemical compounds as recommended [1] [2] by the International Union of Pure and Applied Chemistry (IUPAC). It is published in the Nomenclature of Organic Chemistry (informally called the Blue Book). [3]
The Geneva Nomenclature of 1892 was created as a result of many other meetings in the past, the first of which was established in 1860 by August Kekulé. Another entity called the International Association of Chemical Societies (IACS) existed, and on 1911, gave vital propositions the new one should address: [ 2 ]
The IUPAC Nomenclature for Organic Chemical Transformations is a methodology for naming a chemical reaction.. Traditionally, most chemical reactions, especially in organic chemistry, are named after their inventors, the so-called name reactions, such as Knoevenagel condensation, Wittig reaction, Claisen–Schmidt condensation, Schotten–Baumann reaction, and Diels–Alder reaction.
IUPAC Nomenclature of Organic Chemistry, also known as the "Blue Book", is a website published by the Advanced Chemistry Department Incorporated with the permission of IUPAC. This site is a compilation of the books A Guide to IUPAC Nomenclature of Organic Compounds and Nomenclature of Organic Chemistry. [58]
[1] Preferred IUPAC names are applicable only for organic compounds, to which the IUPAC (International Union of Pure and Applied Chemistry) has the definition as compounds which contain at least a single carbon atom but no alkali, alkaline earth or transition metals and can be named by the nomenclature of organic compounds [2] (see below).
A full edition was published in 1979, [1] an abridged and updated version of which was published in 1993 as A Guide to IUPAC Nomenclature of Organic Compounds. [2] Both of these are now out-of-print in their paper versions, but are available free of charge in electronic versions.
This naming method generally follows established IUPAC organic nomenclature. Hydrides of the main group elements (groups 13–17) are given the base name ending with -ane, e.g. borane (B H 3), oxidane (H 2 O), phosphane (P H 3) (Although the name phosphine is also in common use, it is not recommended by IUPAC).
Organic molecules with more than one functional group can be a source of confusion. Generally the functional group responsible for the name or type of the molecule is the 'reference' group for purposes of carbon-atom naming. For example, the molecules nitrostyrene and phenethylamine are quite similar; the former can even be reduced into the latter.
