This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The synthesis of novel proline-based N-heterocyclic carbene ligands has been accomplished. These types of imidazolium salts can be used as building blocks for the synthesis of more sophisticated N-heterocyclic carbene precursors. The proline amino acids are shown to be compatible with peptide synthetic methods by incorporation into tripeptides. The approaches to a variety of bidentate ligand precursors was reported. A number of the ligands synthesized were bound to rhodium through transmetallation of a silver-NHC complex.

Book Synopsis N-heterocyclic Carbenes by : Carol A. Quezada
Download or read book N-heterocyclic Carbenes written by Carol A. Quezada and published by . This book was released on 2005 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This dissertation discusses the synthesis of different N-heterocyclic carbene precursors, the synthesis of an N-heterocyclic carbene from the precursor, the synthesis of N-heterocyclic carbene complexes of platinum and rhodium, as well as the transfer of N-heterocyclic carbenes from silver to rhodium, and to a smaller extent about the synthesis of previous heterocyclynes. In Chapter 1, the properties and preparation of N-heterocyclic carbenes and carbene salts are discussed. The bonding of N-heterocyclic carbenes as opposed to the bonding of Fischer and Schrock carbenes to metal centers is reviewed. The synthesis of platinum complexes of N-heterocyclic carbenes is illustrated. The synthesis of some of the many heterocyclynes with platinum at the corners is also discussed. The synthesis of the first silver N-heterocyclic carbene complex to use silver(I) oxide is discussed as well as the transfer of the carbene from silver to other metals with an emphasis on the transfer to rhodium. The synthesis of the various rhodium complexes of N-heterocyclic carbenes is also discussed. In Chapter 2 the synthesis of the first bis(N-heterocyclic carbene) complex of platinum is discussed as well as the synthesis of the building blocks to form the heterocyclyne. The high yield synthesis of the heterocyclyne composed of N-heterocyclic carbene platinum complexes at the corners and butadiyde fragments on the periphery is illustrated. In Chapter 3 the syntheses of the N-heterocyclic carbene complexes of silver are reported as well as the first transfer of a carbene from silver to rhodium trichloride hydrate, a necessary step in the direction of using N-heterocyclic carbene complexes of rhodium as radiopharmceuticals. An alternate approach to the synthesis of a rhodium N-heterocyclic carbene complex is also discussed."--Page iii-iv.

Book Synopsis Synthesis and Applications of Poly N-heterocyclic Carbenes and Investigation of Aldimine Coupling by : Adam Bradley Powell
Download or read book Synthesis and Applications of Poly N-heterocyclic Carbenes and Investigation of Aldimine Coupling written by Adam Bradley Powell and published by . This book was released on 2010 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design, synthesis, characterization and application of carbene-based metallopolymers are described herein. Metallopolymers have found wide applications in the fields of photovoltaics, energy storage and electrochromic windows. The incorporation of N-heterocyclic carbene (NHC) functionalities into a polymerizable scaffold would allow for many different metals to be attached in a facile and high-yielding manner. Such complexes could be functionalized onto surfaces and utilized as either spectroscopic or antimicrobial devices. Early attempts in our lab focused on utilizing bis(thiophene) diimines (instead of NHCs) as scaffolds for metal chelation and polymerization. This approach was unsuccessful due to the lability of the diimine moiety under electrochemical cycling and the thiophene moieties were not able to undergo polymerization. In order to more fully understand the key transformation in synthesizing the thiophene-substituted diimines, a comprehensive investigation of the aldimine coupling transformation was undertaken. A high concentration of substrate and catalyst was determined to be the most important factor in obtaining high yields of the dimerized products. Green solvents such as acetonitrile and hexanes could be used for the dimerization reaction when the cyanide counteranion was changed from sodium to tetrabutylammonium. The steric limitations were systematically identified and a series of possible substrates have been ruled out as viable candidates for dimerization. Applying the experience gleaned from earlier reports, the first example of an NHC polymer was prepared in which the monomer features an NHC functional group orthogonally connected to its main chain. A polymerizable imidazolylidene-AuCl complex containing pendant bithiophene moieties was prepared by a high yielding, multistep procedure. Oxidative electropolymerization of this monomer afforded the desired polymer (Au[NHC]Cl)n, which was characterized on the basis of electrochemical studies as well as by X-ray crystallography, photoelectron and UV-vis spectroscopy. The methodology described above was expanded to develop a series of analogous poly(N-heterocyclic carbene) complexes with appended entities (M = Ir, Au, Ag, or S)and found to be electrochromic. Most of the polymers exhibit an intense absorbance wave at 700 nm under oxidative conditions which is attributable to the formation of polaron excitations along the polymer main chain. The presence of a transition metal significantly increased the electrochromic character of the polycarbene system. The iridium-containing polymer was found to possess significant near-infrared (NIR) absorbance at 1100 nm in which the metal moiety effectively functions as an electron sink. Electrochemical analysis of the polymer thin films revealed that they exhibit highly reversible electrochromic activities.

Available in PDF, EPUB and Kindle. Book excerpt: This brief describes studies conducted by the authors on mid-size drugs utilizing peptides and peptidomimetics, and on the development of anti-HIV agents. Peptides are important biological molecules and have various physiological actions. Peptide-based drug discovery may help bring about the development of useful medicines that are highly safe and show potent pharmacological effects in small doses. Recently, it has been shown that there is an important drug-like space in the mid-sized region between low- and high-molecular-weight compounds. Thus, mid-size drugs such as peptide compounds are being focused on. To date, several peptidomimetics that mimic primary, secondary, and tertiary structures of peptides have been developed to maintain and improve biological activities and actions of peptides. In this book, the features and advantages of mid-size drugs are described in detail. In addition, the merits of utilizing peptidomimetics in the development of mid-size drugs are referred to. Understanding such peptide-derived mid-size drugs will lead to a comprehensive expansion of medicinal chemistry.
