APPENDIX 2
Usual detachable prefixes used in substitutive nomenclature
The symbol * designates the preferred IUPAC prefix name or preselected name, for example:
acetamido* = acetylamino; acetylamino = acetamido*.
m
Prefixes that are not recommended are followed by the mention ‘see’ followed by the preferred
prefix, for example ‘chloroxy: see chloryl*’. No formula is given for the entry ‘chloroxy’. As a
counterpart, the preferred prefix is followed by the mention ‘not’ followed by the prefix that is not
recommended, for example: chloryl* (not chloroxy).
