The material of the second edition has been revised with two principal aims in mind. The first is to bring the contents up to date. To this end, Chapter 1 and several parts of other chapters have been rewritten, the references have been updated (with more emphasis given to recent review articles) and several new reaction schemes have been introduced. These new schemes are intended to illustrate aspects of heterocyclic chemistry that are becoming more important. Organopalladium and other organometaUic species are increasingly used in ring synthesis and in substitution reactions; some of the new schemes provide examples. New applications of heterocyclic compounds as pharmaceuticals, as intermediates in organic synthesis and as ligands are also illustrated. Preface to the third edition.
