This book serves as a supplement to The Pyrazines, Volume 41 of the Chemistry of Heterocyclic Compounds series. It covers the literature published between 1979 and 2000, and–together with Volume 41–provides a complete, up-to-date reference for heterocyclic chemists. It emphasizes practical approaches to pyrazine chemistry, offers a full appendix of all simple pyrazines up to 2000, and features detailed coverage of the following topics:

• Systematic descriptions of all primary synthetic routes to pyrazines
• Other preparative routes to alkylpyrazines and their reactions
• Halogenopyrazines and their synthetic uses
• Oxypyrazines and trivial names for pharmaceutical or agrochemical pyrazines
• Thiopyrazines
• Amino-, nitro-, and other similar pyrazines and their reactions
• Pyrazinecarboxylic acids and their derivatives

The supplement features extensive cross-references to the original volume and uses chemical nomenclature as per current IUPAC recommendations
