Appendix: Trivial and Abbreviated Names for Compounds with Radical Centers on Carbon Atoms
List A. Names retained in "A Guide to IUPAC Nomenclature of Organic Compounds", Recommendations 1993 (ref 5)
* Where appropriate, the suffixes "-ylidene" and "-ylidyne" are used with the trivial and abbreviated names given here (see RC-81.1.3.2).
** This name is used for unsubstituted structures only; see Rule A-2.25 (ref 1)
*** This name is included in "A Guide to IUPAC Nomenclature of Organic Compounds", Recommendations 1993 (ref 5), but substitution is not allowed.
**** This name is included in "A Guide to IUPAC Nomenclature of Organic Compounds", Recommendations 1993 (ref 5), but substitution is allowed only on the ring.
List B. Names not retained in "A Guide to IUPAC Nomenclature of Organic Compounds", Recommendations 1993 (ref 5), but included in the 1979 IUPAC Organic Rules (ref 1)
