Recognising the critical need for bringing a handy reference work that deals t only with the most popular reagents in synthesis to the laboratory of practising organic chemists, the editors of the acclaimed 'Encyclopedia of Reagents for Organic Synthesis' (EROS) have selected the most important and useful reagents employed in contemporary organic synthesis. This book presents articles on the most fundamental and versatile reagents for effecting organic transformations that were originally included in EROS. In selecting candidate entries for inclusion in this particular collection, the editors adopted a broad set of criteria for defining what exactly constitutes an acidic or basic reagent. Each article contains all of the information found in EROS as well as expanded related reagents listings. Additional new listings of recently published review articles and mographs are included, as well as relevant 'Organic Syntheses' procedures that deal with either the preparations or reactions of the featured reagents. This thorough and comprehensive handbook will have widespread appeal.
