Chemical Abstracts Subject

Preparations appear in the alphabetical order of common names of the compounds. Eor convenience in surveying the literature concerning any preparation through Chemical Abstracts subject indexes, the Chemical Abstracts indexing name for each compound is given as a subtitle if it differs from the common name used as the title. 

The primary chemical literature has been surveyed up to the end of 1990. Chemical Abstracts subject and chemical substance indexes have been searched up to and including Volume 110. References appeared in Volumes 111 and 112 and a few more references from the later literature have been added to the Appendix (Chapter 7, Section D). 

In preparing this article, the primary chemical literature through July of 1996 was surveyed. Chemical Abstracts Subject and Chemical Substance Indexes through and including Volume 124 were searched. Throughout this article, the name and numbering style favored by Chemical Abstracts is used, and this style is indicated on Schemes 1-3. 

This review covers the literature in primary journals to early 1981 and in Chemical Abstract Subject Indexes to Volume 94. The names used are those adopted by Chemical Abstracts, and the numbering system is [1,2,3) etc. for triazoles rather than the v- or s- symbols.

Chemical Abstracts Subject Index, 1962. The Index to Vol. 56 of Chemical Abstracts inaugurated some definite changes in inorganic nomenclature practices related to indexing. The 1957 lUPAC Report was adopted with certain exceptions. Some of these exceptions merit mention here. 

It is the custom of Chemical AbstraHs to publish an introduction to its Subject Indexes. The indexes are built to stand on their own feet. The introduction is not essential to the ready and effective use of a Chemical Abstracts Subject Index. Nevertheless, for the best results in the use of any index, the user must meet the index maker part way in an understanding of the indexing problem and in particular of nomenclature. The information in the Subject Index introductions is put there to help, and its use is recommended to the searcher who is doing more than incidental searching. 

In the present review the primary chemical literature up to the end of 1981 has been surveyed. Chemical Abstracts Subject and Chemical Substance Indexes up to and including Volume 94 have been searched. Throughout this chapter the name and numbering style favored by Chemical Abstracts is used, i.e., pyrido[l,2-a]pyrimidine for ring system (1). Earlier names to designate the pyrido[l,2-a]pyrimidine derivatives include 1,2-divinylene-pyrimidine (for numbering cf. 2), l,2-(dihydropyrido-r,2 )-5,6-dihydro-pyrimidine, malonyl-a-aminopyridine, 4,10-dihydro-l,10-diazanaphthalene...
