Science of Synthesis: Houben-Weyl Methods of Molecular Transformations is the entirely new edition of the acclaimed reference series, Houben-Weyl, the standard synthetic chemistry resource since 1909. This new edition is published in English and will comprise of 48 volumes published between the years 2000 and 2008. Science of Synthesis is a quality reference work developed by a highly esteemed editorial board to provide a comprehensive and critical selection of reliable organic and organometallic synthetic methods. Science of Synthesis is designed to be the first point of reference when searching for a synthesis strategy. This volume covers the synthesis of five-membered heterocyclic compounds with an oxygen-, sulfur-, nitrogen-, selenium-, tellurium-, or phosphorus-containing heterocycle fused to one or two benzenoid rings. Volume 10 presents selected procedures for the synthesis of benzoannulated five-membered hetarenes. It covers the synthesis of heterocyclic compounds with widely differing stabilities and chemical and physical properties ranging from unstable hetarenes, such as benzo[c]furans, to very stable dibenzohetarenes, such as dibenzothiophene.
