Nomenclature for the C60-Ih and C70-D5h(6) Fullerenes
(IUPAC Recommendations 2002)

Fu-9. Spiro Fullerenes

Continued from Fu-8


Fu-9. Spiro Fullerenes

Fullerenes cannot themselves form spiro compounds directly and, as mentioned earlier, spiro ring systems are not to be used as fusion components with fullerenes.

Spiro fullerenes formed from homofullerenes and fullerenes fused to organic rings follow the normal procedures for naming organic spiro systems that contain at least one polycyclic ring system (ref. 11). Spiro fullerene parent hydrides will not necessarily have unprimed numbers as locants.

Examples:


Spiro[cyclohexane-1,1'a-[1(9)a]homo(C60-Ih)[5,6]fullerene]


2",7"-Dinitrospiro[cyclopropa[1,9](C60-Ih)[5,6]fullerene-3',9"-fluorene]


Dispiro[cyclopropane-1,3"-cyclobuta[1,9](C60-Ih)[5,6]fullerene-4",2'''-[1,3]dioxane]


Dispiro[cyclohexane-1,3"-dicyclopropa[1,9:52,60](C60-Ih)[5,6]fullerene-3''',1''' '-cyclohexane] error details
