Conjunctive Nomenclature

Rule C-52

52.1 - For all purposes in conjunctive nomenclature the side chain is considered to extend only from the principal group to the cyclic component. Any other chain members, even those extending this side chain terminally, are named as substituents, appropriate prefixes being placed before the name of the cyclic component.

Example to Rule C-52.1

52.2 - When a cyclic component carries more than one identical side chain, the name of the cyclic component is followed by di-, tri-, etc. (to indicate the number of such side chains), and then by the name of the acyclic component, and it is preceded by the locants for the side chains.

Example to Rule C-52.2

52.3 - When side chains of two or more different kinds are attached to a cyclic component, only the senior side chain (see Subsection C-0.13) is named by the conjunctive method. The remaining side chains are named as prefixes.
