Nomenclature of Fused and
Bridged Fused Ring Systems
Synopsis: These recommendations constitute a comprehensive documentation
for naming fused ring systems and bridged fused ring systems. It expands and
extends the recommendations given in rules A-21, A-22, A-23, A-34, B-3 of
the IUPAC Nomenclature of Organic Chemistry, Sections A, B, C, D, E, F
and H, 1979 and rule R-2.4.1 of A Guide to IUPAC Nomenclature of Organic
Compounds, 1993. Any ring system with two or more rings ortho- or ortho-

are ortho-fused together have only two atoms and one bond in common. The nomenclature
of spiro systems and von Baeyer nomenclature will be considered in separate
