Von Baeyer names

Buckminster Fuller was the inventor of self-supporting polygon frameworks, e.g., of pavilions. Synonyms (root)ballene, buckminsterfullerenc( BF ), carbosoccer, soo r(ball)ene, spherene. The proposed bridged-fused ring system and von-Baeyer names and numberings vary. 

The two most commonly applied systems for naming polycyclic parents are in some ways complementary. Fusion nomenclature provides names for structures containing the maximum number of non-cumulative double bonds von Baeyer nomenclature (Section 1.02.3.4) names fully saturated structures. Thus names for partially hydrogenated structures can be arrived at either by adding hydro prefixes to fusion names or ene , diene , etc. suffixes to von Baeyer names (see examples 29 and 30). If needed, rules are available for... 

For bicyclic structures the von Baeyer name consists of the prefix bicyclo-, followed in square brackets by the numbers of carbon atoms separating the bridgeheads on the three possible routes from one bridgehead to the other, followed in turn by the name of the alkane (or other homogeneous hydride, or repeating unit hydride) containing the same number of atoms in the chain as the whole bicyclic skeleton (examples 55-57). Replacement nomenclature can be applied to hydrocarbon names (example 58). 

The rules for identifying the main ring, the main bridge and the secondary bridges and for numbering the structure are complex (see lUPAC Blue Book Rules A-31 and A-32 B-79MI10200)) and not always easy to apply this probably accounts for the appearance of many incorrect von Baeyer names in the literature. 

Von Baeyer name a name that describes aUcycUc bridged systems e.g., bicyclo [2.2-1 hepume.

Many bridged ring systems are named by the von Baeyer system. Von Baeyer names are used mostly for bridged ring systems and occasionally for nonbridged ring systems. Examples of von Baeyer names are bicyclo[3.2.1]octane and tricyclo[7.4.1.0 ]tetradecane. 

Another comprehensive organic nomendature was proposed by Terent ev ti ol [30]. Ring systems are numbered uniquely by picking a path, and acyclic compounds are numbered and named uniquely as sums of unbranched components. The name of the first example in Figure 10 is similar to a von Baeyer name. The numerical data are read as follows. 

The uniqueness of these so-called von Baeyer names is ensured by requirements such as... 

Adolf von Baeyer named this compound in honor of a woman named Barbara... 

For the following compounds Chem. Abstr. incomprehensibly uses the von Baeyer names bicyclo[4.2.0]octa-l,3,5,7-tetraene and lif-bicyclo[4.1.0] hepta-l,3,5-triene that totally disregard the aromatic character of these compounds.
