This book was released on 2013 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the reactivity of metal complexes with molecular oxygen will facilitate the development of catalysts that can enable the widespread use of molecular oxygen as an oxidant for organic synthesis. This thesis presents two new classes of reactions between metal complexes and molecular oxygen. Neutral five-coordinate Pt complexes were tested for reactivity in the presence of molecular oxygen. In arene solution, the complexes (t̳B̳u̳̳M̳e̳2̳ nacnac)PtMe3 (1, t̳̳B̳u̳M̳e̳2̳ nacnac- = [((4-tBu-2,6-Me2C6H2)NC(CH3))2CH]-), (M̳e̳3̳ Me-nacnac)PtMe3 (2, M̳e̳3̳ Me-nacnac- = [((2,4,6-Me3C6H2)NC(CH3))2CCH3]-), and (t̳B̳u̳2̳ PyPyr)PtMe3 (3, t̳B̳u̳2̳ PyPyr- = 3,5-di-tert-butyl-2-(2-pyridyl)pyrrolide) reacted immediately with oxygen to form peroxo species in which two oxygen atoms bridge between the metal center and a carbon atom in the ligand backbone. In contrast, no reaction between ( i̳P̳r̳2̳ AnIm)PtMe3 (4a, i̳P̳r̳2̳ AnIm− = [o- C66H4-{N(C6H3 i Pr2)}(CH=NC6H3 i Pr2)]−) or (M̳e̳3̳ AnIm)PtMe3 (4b, M̳e̳̳3̳ AnIm− = [o-C6H4- {N(C6H2Me3)}(CH=NC6H2Me3)]−) and oxygen was observed. As activation of oxygen by five- coordinate PtIV species was found to involve cooperation between the metal center and the ligand, the ability of the ligand to participate in the oxygen binding appears to be a vital component. Oxygen atom transfer reactions of the novel peroxo species are also presented. In a separate study, an unusual reaction involving the activation of both molecular oxygen and a C-H bond at the same metal center was investigated. Pd(P(Ar)(tBu)2)2 (15, Ar = naphthyl) was found to react with molecular oxygen at room temperature in arene solvent to form a hydroxide dimer in which one equivalent of phosphine per Pd was lost and the remaining phosphine was cyclometalated through the naphthyl ring. At low temperature, two intermediates were observed. The nature of these intermediates suggests a mechanism involving initial reaction of Pd(P(Ar) (tBu)2)2 with O2 followed by the C-H activation step. In a final chapter unrelated to oxygen reactivity, the generation and characterization of a gold III̳-alkene complex by NMR and X-ray crystallography is presented. Such species have been proposed as intermediates in catalytic reactions but until recently none had been observed.

Available in PDF, EPUB and Kindle. Book excerpt: Integrates solid-phase organic synthesis with palladium chemistry The Wiley Series on Solid-Phase Organic Syntheses keeps researchers current with major accomplishments in solid-phase organic synthesis, providing full experimental details. Following the validated, tested, and proven experimental procedures, readers can easily perform a broad range of complex syntheses needed for their own experiments and industrial applications. The series is conveniently organized into themed volumes according to the specific type of synthesis. This second volume in the series focuses on palladium chemistry in solid-phase synthesis, exploring palladium catalysts and reactions, procedures for preparation and utilization, ligands, and linker reactions. The first part of the volume offers a comprehensive overview of the field. Next, the chapters are organized into three parts: Part Two: Palladium-Mediated Solid-Phase Organic Syntheses Part Three: Immobilized Catalysts and Ligands Part Four: Palladium-Mediated Multifunctional Cleavage Each chapter is written by one or more leading international experts in palladium chemistry. Their contributions reflect a thorough examination and review of the current literature as well as their own first-hand laboratory experience. References at the end of each chapter serve as a gateway to the field's literature. The introduction of palladium-mediated, cross-coupling reactions more than thirty years ago revolutionized the science of carbon-carbon bond formation. It has now become a cornerstone of today's synthetic organic chemistry laboratory. With this volume, researchers in organic and medicinal chemistry have access to a single resource that explains the fundamentals of palladium chemistry in solid-phase synthesis and sets forth clear, step-by-step instructions for conducting their own syntheses.

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-

Among those strategies, catalysis and the design of new processes that avoid the use of toxic reagents have been the focus of intense research.
Download or read book Metal Complexes written by Peter Maitlis and published by Elsevier. This book was released on 2012-12-02 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Organic Chemistry of Palladium, Volume 1: Metal Complexes deals with the number of organic reactions that can be catalyzed by palladium, particularly as regards the structures bonding, and reactions of the metal complexes. The book discusses monodentate ligands which are either neutral (carbonyls, isonitriles, carbenes) or anionic (methyl, phenyl, ethynyl, hydride). The text also examines the complexes formed by 1,3-. 1,4-, and 1,5-diolefins where four carbon atoms are bound to the metal. Palladium (II) can undergo a reaction with the 1,3-dienes and results in a ?-allylic complexes where only three carbon atoms are coordinated to the metal. (The bonding situation in complexes 1,4- and 1,5-dienes, where no great interaction between the olefins are similar to that in monoolefin complexes, is straightforward), Olefins can also react with palladium chloride in protic solvents to produce ketones (or aldehydes) or organic coupling products. Some experiments conducted by Huttel et al shows that some palladium was precipitated from the reactions giving lower yields, resulting in various aldehydes and ketones as by products. The book also discusses cyclopentadienyl and benzene complexes. The text can prove beneficial for researchers, investigators and scientists whose works involve organic chemistry, analytical chemistry, physical chemistry and inorganic chemistry.
Download or read book Pd Palladium written by William P. Griffith and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: With platinum and rhodium, palladium is one of the most important members of the platinum metal group. The last Gmelin treatment of it was in 1942, and knowledge of its properties and chemistry has made enormous strides since then. This volume is primarily concerned with binary compounds and with the coordination complexes derived from them. Although it is a member of the nickel-palladium-platinum triad, it more closely resernblas platinum in its binary and coordination chemistry, though being a second-row transition element it displays less tendency than does platinum to assume higher oxidation states. ln heterogeneous and homogeneous catalysis, referred to at appropriate points, palladium and its complexes are of great importance in bulk and fine chemieals production, effecting a wide variety of organic transformations. The arrangement of material in this volume follows the traditional Gmelin arrangement. Within each category of compounds or complexes the material is arranged, as usual, in order of ascending metal oxidation states (e. g., palladium(ll) precedes palladium(IV)). The chemistry of the palladium-hydrogen system is so large that it merits a separate volume, so this book starts with the binary oxides and oxopalladates followed by hydroxides, hydroxo complexes and aquo complexes. Then nitrides and nitrates are treated. They are followed by the large chapters on halides and their complexes (172 pages). The largest single chapter in this volume (11 0 pages) deals with chlorides, chloropalladates and other chloro complexes.
