Download or read book (N-heterocyclic-carbene)Copper(I)-catalyzed Carbon-carbon Bond Formation Using Carbon Dioxide written by Gergely Sirokman and published by . This book was released on 2007 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents work towards the development of a new catalytic C-C bond forming reaction. Alkynes and olefins insert into [(IPr)CuH]2 (IPr = N, N-bis-(2,6-diisopropylphenyl)-1,3-imidazol-2-ylidene) to give copper vinyl and copper alkyl complexes. These copper complexes insert CO2 into the Cu-C bond to form copper acrylate and copper carboxylate complexes. Acrylic and carboxylic acids can be isolated by hydrolysis. A catalytic cycle based on (IPr)copper(I) was developed. Alkynes undergo reductive carboxylation to give acrylic acids in moderate yields. Unexpected interactions between several components of the catalytic system led to a number of side reaction, most importantly between [(IPr)CuH]2 and the product silyl acrylate. The use of silylcarbonate salts to desylilate the product enhanced yield. In addition, silylcarbonates can also serve as a source of CO2.

Download or read book Development of a New Heterocycle-Forming Reaction and Kinetic Resolution with N-Heterocyclic Carbenes written by Yinli Wang and published by Springer. This book was released on 2019-07-10 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, the author focuses on exploring new organocatalytic transformations under operationally simple and environmentally friendly reaction conditions. Two new types of catalytic reactions promoted by N-heterocyclic carbenes (NHCs) are described. The oxa- and azacycle-forming reactions of sulfonylalkynols and sulfonylalkynamides are broadly considered to be a new type of activation mode in NHC chemistry, wherein the bond formation with internal O- and N-nucleophiles occurs at the γ-position of the propargyl sulfones with 1,2-sulfonyl migration. The resulting oxa- and azacycles are core structures in many biologically significant compounds and medicinally important agents. In addition, the book develops the chiral NHC-catalyzed kinetic resolution of α-hydroxy carboxylic acid derivatives based on chiral recognition of the substrate–cocatalyst complex. In this carboxylate cocatalyst-assisted chiral acylation, the reaction rate acceleration and selectivity enhancement are interpreted in terms of the reversible complexation of the substrate and carboxylate cocatalyst, which is verified by control experiments and measured using analytical methods. The findings described here reveal a promising new aspect of not only NHC catalysis but also identifying novel catalysis systems.

Book Synopsis Cleavage of Carbon-Carbon Single Bonds by Transition Metals by : Masahiro Murakami
Download or read book Cleavage of Carbon-Carbon Single Bonds by Transition Metals written by Masahiro Murakami and published by John Wiley & Sons. This book was released on 2015-09-21 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Edited by leading experts and pioneers in the field, this is the first up-to-date book on this hot topic. The authors provide synthetic chemists with different methods to activate carbon-carbon sigma bonds in organic molecules promoted by transition metal complexes. They explain the basic principles and strategies for carbon-carbon bond cleavage and highlight recently developed synthetic protocols based on this methodology. In so doing, they cover cleavage of C-C bonds in strained molecules, reactions involving elimination of carbon dioxide and ketones, reactions via retroallylation, and cleavage of C-C bonds of ketones and nitriles. The result is an excellent information source for researchers in academia and industry working in the field of synthetic organic chemistry, while equally serving as supplementary reading for advanced courses in organometallic chemistry and catalysis.
Book Synopsis Biotransformations in Organic Chemistry by : Kurt Faber
Download or read book Biotransformations in Organic Chemistry written by Kurt Faber and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of natural catalysts - enzymes - for the transformation of non-natural is not at all new: they have been used for more man-made organic compounds than one hundred years, employed either as whole cells, cell organelles or isolated enzymes [1]. Certainly, the object of most of the early research was totally different from that of the present day. Thus the elucidation of biochemical pathways and enzyme mechanisms was in the foreground of the reasearch some decades ago. It was mainly during the 1980s that the enormous potential of applying natural catalysts to transform non-natural organic compounds was recognized. What started as a trend in the late 1970s could almost be called a fashion in synthetic organic chemistry in the 1990s. Although the early euphoria during the 'gold rush' in this field seems to have eased somewhat, there is still no limit to be seen for the future development of such methods. As a result of this extensive, recent research, there have been an estimated 5000 papers published on the subject [2]. To collate these data as a kind of 'super-review' would clearly be an impossible task and, furthermore, such a hypothetical book would be unpalatable for the non-expert.
Book Synopsis C-C Bond Activation by : Guangbin Dong
Download or read book C-C Bond Activation written by Guangbin Dong and published by Springer. This book was released on 2014-09-18 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: The series Topics in Current Chemistry presents critical reviews of the present and future trends in modern chemical research. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field. Review articles for the individual volumes are invited by the volume editors. Readership: research chemists at universities or in industry, graduate students

Book Synopsis N-heterocyclic Carbenes by : Silvia Díez-González
Download or read book N-heterocyclic Carbenes written by Silvia Díez-González and published by Royal Society of Chemistry. This book was released on 2011 with total page 469 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last fifteen years, N-heterocyclic carbenes (NHCs) have mostly been used as ancillary ligands for the preparation of transition metal-based catalysts. Compared to phosphorus-containing ligands, NHCs tend to bind more strongly to metal centres, avoiding the necessity for the use of excess ligand in catalytic reactions. The corresponding complexes are often less sensitive to air and moisture, and have proven remarkably resistant to oxidation. Recent developments in catalysis applications have been facilitated by the availability of carbenes stable enough to be bottled, particularly for their use as organocatalysts. This book shows how N-heterocyclic carbenes can be useful in various fields of chemistry and not merely laboratory curiosities or simple phosphine mimics. NHCs are best known for their contribution to ruthenium and palladium-catalysed reactions but the scope of this book is much broader. The synthesis of NHC ligands and their corresponding metal complexes are covered in depth. Moreover, the biological activity of NHC-containing complexes, as well as an overview of their theoretical aspects are included. Such metal species are further examined, not only in terms of their catalytic applications, but also of their stereoelectronic parameters and reactivity/stability. Finally, special attention is given to the hot topic of organocatalysis. The book will be of interest to postgraduates, academic researchers and those working in industry.
