Conjunctive nomenclature

Especially for systems with several identical substituents of senior parent structure character the conjunctive method offers manifest advantages.

As has already been conveyed in the discussions relating to parent structures, specific naming rules (on whose necessity opinions are divided) are to be obeyed for compounds assembled from identical cyclic components. The same holds for assemblies of identically substituted subunits, of

When the aldehyde group is directly attached to a carbon atom of a ring system, the suffix -carbaldehyde is added to the name of the ring system, e.g., 2-naphthalenecarbaldehyde. When the aldehyde group is separated from the ring by a chain of carbon atoms, the compound is named (1) as a derivative of the acyclic system or (2) by conjunctive nomenclature, for example, (1) (2-naphthyl)propionaldehyde or (2) 2-naphthalenepropionaldehyde.

Conjunctive nomenclature may be used for naming cyclic adds. It is applied to any ring system attached by a single bond to one or more acyclic hydrocarbon chains, each of which hears only one principal functional group. 

The combination of core and terminal unit names resembles conjunctive nomenclature. The multiplicity of branching (cascading) from the core unit is indicated by a bracketed numeral immediately following the name of the core unit if locants are necessary, they are also enclosed within the brackets, following and separated by a hyphen from the multiplicity numeral. 

G) If the principal group is attached to a chain and that in turn to a ring, the British author may treat the cyclic radical as a substituent into the chain or conjunctive nomenclature (p. 79) may be used. 

Conjunctive nomenclature is particularly suitable for systems multiply substituted with identical functional parents but is generally used by Chem. Abstr. for any type of saturated linear monocarboxylic acid bearing a ring as substituent group. 

Alcohols and phenols are generally named by the substitutive method although Chem. Abstr. applies conjunctive nomenclature whenever possible, i.e. for chain alcohols with ring substituent groups... 

Figure 6.33 One method of differentiating substituents on an aliphatic chain that is attached to an aromatic ring system is conjunctive nomenclature. Positions on the chain are assigned Greek letters with a-as the position adjacent to the substituent of highest priority. This is shown in the example on the left. The right-hand structure, p-amino-y-methyl-2-naphthylpropanol, provides another example.
