Appendix 2

DETACHABLE PREFIXES USED FOR SUBSTITUTIVE NOMENCLATURE

The symbol * designates the preferred prefix (for example: acetamido* = acetylamino; acetylamino = acetamido*) or the preselected prefix (for example: sulfanyl* = thio).

Prefixes that are not recommended are followed by the mention ‘see’ followed by the preferred or preselected prefix (for example: ‘chloroxy: see chloryl*’. No formula is given for the entry ‘chloroxy’. As a counterpart, the preferred or preselected prefix is followed by the mention ‘not’ and the prefix that is not recommended enclosed in appropriate enclosing marks [for example: chloryl* (not chloroxy)].
