We follow the 1979 IUPAC recommendations summarized in Polynuclear Aromatic Hydrocarbons Nomenclature Guide (Loening et al. 1990). The American Chemical Society also publishes the Ring Systems Handbook, which, ca. 1990, contained structural diagrams for over 70,000 unique ring systems (American Chemical Society, 1977 to present).

The group of compounds represented by this chapter title embraces a very wide range of possible ring systems. Even the list of 160 compounds in the Ring Systems Handbook [Pg.921]

For the organic chemist, knowledge of, and access to, the more familiar components of the printed products of Chemical Abstracts is still desirable CA abstracts CA Volume Indexes and CA Collective Indexes CA Index Gnide CAS Source Index (CASSI) Registry Handbook Number Section the Ring Systems Handbook and CA Selects. 

Various publications from the Chemical Abstracts Service can be nsed to find the name of a known ring system. The most comprehensive sonrce of ring system names is the Ring Systems Handbook (RSH). Entries are in ring analysis order, i.e., according to the following hierarchy of ring data ... 

To understand a patent usually requires the reader to draw some of the many structures of the compounds cited. Complete structural drawings express knowledge of the long systematic chemical names compiled in the claims and in the preparative and working examples. Often, to compose names from structures, or draw structures from names, calls for the help of a librarian or another specialist trained in nomenclature. A cornucopia of nomenclature is The Ring System Handbook. ... 

A variety of methods have been used in the primary literature to number (5,5) bicyclic heterocycles. For consistency, the authors have adopted the system used in the Chemical Abstracts Ring Systems Handbook (1993 Edition). 

The most important source of information on heterocyclic and isocyclic systems is the Ring Systems Handbook of the Chemical Abstracts Service (CAS) published by the American Chemical Society. The 1988 edition is arranged as follows ... 

Under the admirably liberal policy of the founding and subsequent editors (Arnold Weissberger, Edward C, Taylor, and Peter Wipf), individual authors have sometimes used outdated or alternative systems of nomenclature perceived as convenient for their particular subject(s). To minimize this complication in the index, nearly all system names therein follow or approximate to those currently recommended in the Chemical Abstracts Service s Ring System Handbook (2003 edition and supplements). 

The Ring Systems Handbook provides access to some 100000 ring and cage systems. 

The Chemical Substance Index shows the structure diagram immediately after the CAS Registry Number. Now it can be ascertained if this is the correct ring system (Fig. 70). The structure diagram of all cyclic parent compounds, i.e. all compounds mentioned in the Index of Ring Systems, are illustrated in the Chemical Substance Index. These ring skeletons are also shown in the Ring Systems Handbook (Sect. 5.1). 

The Ring Systems Handbook (1993 edition) contains all the presently known basic structural skeletons, the parent compounds of cyclic substances, i.e. ring systems without substituents. The handbook includes approximately 84,000 ring and 288 cage systems. It is a complete work of reference which provides access to the systematic CA Index Name, the CAS Registry Number and the molecular formula of a ring system or which describes to a complex substance name the chemical structure. The handbook contains three parts ...
