Available in PDF, EPUB and Kindle. Book excerpt: This handbook and ready reference brings together all significant issues of practical importance in selected topics discussing recent significant achievements for interested readers in one single volume. While covering homogeneous and heterogeneous catalysis, the text is unique in focusing on such important aspects as using different reaction media, microwave techniques or catalyst recycling. It also provides a comprehensive treatment of key issues of modern-day coupling reactions having emerged and matured in recent years and emphasizes those topics that show potential for future development, such as continuous flow systems, water as a reaction medium, and catalyst immobilization, among others. With its inclusion of large-scale applications in the pharmaceutical industry, this will equally be of great interest to industrial chemists.

Available in PDF, EPUB and Kindle. Book excerpt: This book is a compilation of the recent applications of palladium catalysts in organic synthesis. The book demonstrates that it is a highly dynamic research field. This methodology has emerged as a powerful tool for the efficient and chemoselective synthesis of heterocyclic molecules. In the past few years, several strategies have been pointed out to pursue more efficient, sustainable, and environment friendly chemical processes. Among those strategies, catalysis and the design of new processes that avoid the use of toxic reagents have been the focus of intense research.

This book was released on 2012-12-06 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Around 30 years ago the transition metal chemistry received great impulses. In the focus have been reactions of nickel and cobalt and herein especially their carbonyls. Also industrial processes have been developed. When the technical oxidation of ethylene with palladium chloride had been discovered, and a great number oflaboratory reactions, many groups have turned towards this subject. Apart from two important industrial processes - acetaldehyde and vinylacetate from ethylene - a great number of conversions and catalytic reactions with palladium compounds have been researched. Their mechanisms have been cleared up and have con tributed to a better understanding of the complex chemistry of palladium. Last but not least these reactions have also served for more understanding of organic transition metal compounds and catalyses in general. Numerous conventional reactions appear today in a different light. The effects of co-

This book was released on 2013 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research in catalysis particularly cross coupling reactions catalyzed by transition metals is a major field in applied sciences and involves many areas of chemistry. In the last few years, there is upsurge in the area of heterogeneous catalysis for chemical industries. Transition metal chemistry (particularly Pd based) complements traditional functional-group-based chemistry and significantly broadens the scope of organic chemistry. For the past 20 years, numerous research groups have developed new metal complexes and ligands, expanding the scope of these transformations. The importance of these transformations and their impact on synthetic chemistry have been recently recognized by awarding Nobel Prize in Chemistry for the year 2010 to Professor Heck, Negishi and Suzuki jointly.

This book was released on 2005 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phase-Transfer Catalysis (PTC) is a very useful approach and has been widely used in synthetic organic chemistry. A novel class of fluoroanthracenylmethyl PTC catalysts were synthesized and explored for asymmetric glycolate and glycine alkylation. Phosphorous pentoxide was used for the challenging electron-deficient electrophilic aromatic substitution step. These new catalysts proved to have high selectivities for glycine alkylation under mild conditions.

This book was released on 2007 with total page 1130 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have obtained a tetracyclic Heck product with a formal anti-beta -hydride elimination during our post-ARO Pd-catalyzed derivatization studies of dihydronaphthalenes. We found that the yield for this Heck reaction was highly base-dependent, with DABCO being optimal. The catalyst combination of Pd2(dba)3/HP(tBu)3·BF 4 and DABCO was highly efficient for this intramolecular Heck reaction under very mild conditions. Additionally, we observed tandem double Heck reactions, which selectively functionalize two C-Br bonds intra- and intermolecularly. We further developed the concept of selective intramolecular and intermolecular cross-couplings using more general gemdihaloolefin systems, which subsequently led to the development of a variety of heterocycle forming reactions. A tandem C-N/Suzuki coupling of a gemdihalovinylaniline and organoboron reagents including aryl, heteroaryl, alkenylboronic acids (or borate esters) and alkyl boranes afforded a variety of 2-substituted indoles in good to excellent yield. This new method of indole synthesis tolerated various functional groups on all positions of the indole moiety. The orthogonal approach of the sequential copper and palladium-mediated synthesis of 1,2-diarylindoles exploited the availability of diverse organoboron reagents. This new method was successfully applied for the synthesis of three Merck KDR kinase inhibitors in very good overall yields. The Pd-catalyzed tandem couplings of gemdihalovinyl systems were further extended for the synthesis of (1) 2-carbonyl indoles via a C-N coupling, carbonylation, and Suzuki sequence, (2) 2-vinyl indoles via a C-N coupling/Heck reaction sequence, and (3) 2 alkynyl indoles via a C-N/Sonogashira coupling sequence. Furthermore, a Cu-catalyzed tandem Goldberg reaction was developed for the synthesis of imidazoindolones from amino acid-tethered gemdibromoolefins. Preliminary studies towards a modular synthesis of azaindoles from N'-Boc- N'-gemdibromovinyl pyridylamine via a sequential Suzuki/direct arylation protocol was also explored. This new tandem coupling reaction was also successfully extended to two other pharmaceutically important families of heterocycles, azaindoles and thienopyrroles. Suitable substituents (such as alkyl, Boc, and Cbz) on the amino group of the substrate were essential to prevent catalyst poisoning during the tandem process.
