This single-volume supplement contains approximately 3000 new and updated entries extending the coverage of the Dictionary. These are comprised of new entries based on the current literature from mid 1989 to 1990, updated entries containing significant new information which has appeared in the literature in that period and new entries for known compounds based on further literature research by the DOC editors.
The intermediates described in this book include different types of phenols, aldehydes, carboxylic acids and ketones (acetophenones, w-substituted acetophenones, propiophenones, butyrophenones, benzophenones, phenyl ketones and some miscellaneous ketones). The preparation of heterocyclic compounds (O-containing, S-containing, N-containing, N & S-containing) is also described. The synthesis of certain miscellaneous compounds of the type benzyl cyanides, b-ketoesters, chalcones, naphthaquinones, benzoquinones, stilbene and certain catalysts and reagents required for organic synthesis are also described. The present book aims to make available detailed procedures for the synthesis of various intermediates, which are generally required by organic chemists working in various universities, industries and by the research scholars at different levels. No single publication is available describing the intermediates required for organic synthesis. Attempt has been made to describe the best possible procedures with ample experimental details keeping in mind the maximum yield. The authors and their associates have verified all the procedures described.
