Modern organic synthesis has paid much attention to the chemistry of small carbocycles. Vinylidenecyclopropanes (VDCPs), which have strained cyclopropyl group connected with an allene moiety and yet are thermally stable and reactive substances in organic chemistry, are versatile intermediates in organic synthesis. In this volume, Dr. Lixiong Shao, Dr. Jianmei Lu and Prof. Dr. Min Shi review their investigations on the chemistry of VDCPs, mainly including the preparation, the reactivities upon treatment with Lewis or Brønsted acid, as well as transition metal catalysts and some other miscellaneous analogues. The contributions aroused a renaissance of cationic intermediates in the chemistry of VDCPs.
In his thesis, Sohail Shahzad carefully investigates carbon nucleophiles in selenocyclisations, as well as reaction protocols for performing such reactions catalytically. After a comprehensive introduction to the element selenium, the author goes on to report the synthesis of several substrates for carbocyclisation reactions and the use of selenium reagents for the preparation of dihydronaphthalenes. Further chapters detail electrophilic selenium-mediated reactions, and novel strategies using selenium catalysts together with stoichiometric amounts of hypervalent iodine reagents as oxidants to convert stilbene carbosylic acids into the corresponding isocoumarins. This thesis outlines some excellent new synthetic routes which will be useful tools for synthetic organic chemistry in the future.
The first book in the PATAI Series was published in 1964 and the Series will celebrate its 50th Anniversary in 2014. This "Golden Jubilee" is accompanied by the publication of the first volume on the chemistry of organogold. In the history of the PATAI Series there was, so far, no volume dedicated to gold alone. In 1999 we published a volume on The Chemistry of Gold and Silver Compounds. Since then a lot of new chemistry using gold has been developed and it is timely to focus a volume on methods and applications of organogold compounds in organic synthesis, reflecting the enormous progress which has been made in the use of gold compounds as reagents and catalysts. A second area of great importance covered in the book is the use of gold surfaces in the synthesis of peptides, proteins and other natural products. A whole range of applications in the area of biochemistry has resulted from these developments. A third area of interest is the synthesis and engineering of nanostructures, where organogold chemistry has opened the door for a wide range of methods and applications in the field of nanoscience and materials science. As with all new volumes, the chapters are first published online in Patai's Chemistry of Functional Groups. Once a volume is completed online, it is then published in print format. The printed book offers the traditional quality of the Patai Book Series, complete with an extensive index.
Organic Reaction Mechanisms 2010, the 46th annual volume in this highly successful and unique series, surveys research on organic reaction mechanisms described in the available literature dated 2010. It details the latest progress in a wide range of classes of organic reaction mechanisms, including reactions of different compounds and acids and their derivatives, oxidation and reduction, aliphatic substitutions, elimination reactions, and molecular rearrangements, to name a few. An experienced team of authors compiled these reviews, ensuring the quality of selection and presentation.
The elucidation of reaction mechanisms generally requires the carefully designed control of molecular symmetry to distinguish between the many possible reaction pathways. Making and Breaking Symmetry in Chemistry emphasises the crucial role played by symmetry in modern synthetic chemistry. After discussion of a number of famous classical experiments, the advances brought about by the introduction of new techniques, in particular NMR spectroscopy, are exemplified in numerous cases taken from the recent literature. Experimental verification of many of the predictions made in Woodward and Hoffmann's explication of the Conservation of Orbital Symmetry are described. Applications that involve the breaking of molecular symmetry to resolve these and other mechanistic problems in organic, inorganic and organometallic chemistry are presented in the first sections of the book, together with many examples of the detection of hitherto hidden rearrangement processes.Subsequently, under the aegis of making molecular symmetry, examples of the preparation of highly symmetrical molecules found in the organic, organometallic or inorganic domains are discussed. These include Platonic hydrocarbons or boranes, tetrahedranes, cubanes, prismanes, dodecahedrane, fullerene fragments such as corannulene, sumanene or semibuckminsterfullerene, and other systems of unusual geometries or bonding characteristics (Möbius strips, molecular brakes and gears, Chauvin's carbomers, Fitjer's rotanes, persubstituted rings, metal-metal multiple bonds, etc.). The text also contains vignettes of many of the scientists who made these major advances, as well as short sections that briefly summarise key features of important topics that underpin the more descriptive material. These include some aspects of chirality, NMR spectroscopy, and the use of isotopic substitution to break molecular symmetry. A brief appendix on point group symmetry and nomenclature is also helpfully provided.
