Download or read book Direct Synthesis of Metal Complexes written by B.I. Kharisov and published by Elsevier. This book was released on 2018-04-19 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: Direct Synthesis of Metal Complexes provides in-depth coverage of the direct synthesis of coordination and organometallic compounds. The work is primarily organized by methods, but also covers highly relevant complexes, such as metal-polymer coordination compounds. This updated reference discusses recent developments in cryosynthesis, electrosynthesis, and tribosynthesis (popular as it doesn’t require organic solvents), with special attention paid to ‘greener’ methodologies and approaches. Additionally, the book describes physical methods of zero-valent metal interaction with organic matter, including sputtering, ultrasonic treatment and synthesis in ionic liquids. The book presents completely new content as a follow-up to the 1999 Elsevier Science publication Direct Synthesis of Coordination and Organometallic Compounds that was edited by Dr. Garnovskii and Dr. Kharisov. Covers current methods and techniques of metal interactions with organic media leading to metal chelates, adducts, di- and polymetallic complexes, metal-containing macrocycles, supported coordination compounds (i.e., metal complexes on carbon nanotubes), and more Describes reactivities of distinct forms of elemental metals (powders, sheets, nanoparticles (including a host of less-common metal nanostructures) with organic phase (liquid, solid and gaseous) and water Includes experimental procedures, with examples of direct synthesis, at the end of each chapter

Book Synopsis Development of Constrained Geometry Complexes of Group 4 and 5 Metals by : Ryan Thomas Rondo
Download or read book Development of Constrained Geometry Complexes of Group 4 and 5 Metals written by Ryan Thomas Rondo and published by . This book was released on 2010 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Constrained geometry catalysts (CGC) are known to be active in the polymerization and copolymerization of alkenes with a distinct control over polymer tacticity. The tethering of one eta-5-cyclopentadienyl moiety and one pendant donor gives these compounds an accessible metal center as well as ability to maintain their structure throughout the catalytic process. Complexes of this type typically feature one pendant amido donor. Replacement of the pendant amido donor with a nitrogen heterocycle such as an indolyl- or pyrrolyl-group should result in electrophilic metal centers due to reduced N to M pi donation, a consequence of electron delocalization of the nitrogen lone pair in the aromatic system. This dissertation reports the development of a new series of constrained geometry ligands that feature indolyl- and pyrrolyl- donor moieties. In chapter 2, the synthesis and characterization of a series of acetal precursors and their corresponding di(3-methylindolyl)ethane and dipyrrolylethane constrained geometry ligands is reported. Within this report are two new acetal precursors, fluorenyl acetaldehyde diethylacetal, and indenyl acetaldehyde diethylacetal. Also described are the new constrained geometry ligands fluorenyl di(3-methylindolyl)ethane (H3FDI), fluorenyl dipyrrolylethane (H3FDP), indenyl di(3-methylindolyl)ethane (H3IDI), and indenyl dipyrrolylethane (H3IDP). These compounds have been characterized by 1H and 13C NMR spectroscopy as well as mass spectrometry and elemental analysis. The molecular structure of H3FDI THF has been confirmed by X-ray crystallography. This new set of ligands serves as a framework for constrained geometry complexes of group 4 and 5 transition metals. Chapter 3 reports the synthesis and characterization of group 4 and 5 constrained geometry complexes of fluorenyl di(3-methylindolyl)ethane (H3FDI) and indenyl di(3-methylindolyl)ethane (H3IDI). Within this report are the first examples of 3-methylindolyl-based CGC's of group 4 and 5 metals, specifically in the complexes (HFDI)Zr(NEt2)2(THF), (HFDI)Ti(NEt2)2, (IDI)Zr(NEt2), which were prepared using amine elimination methods, and (IDI)Nb(NtBu)(py), (IDI)Nb(NPh), (FDI)Zr(CH3), and (FDI)Ti(CH3), which were prepared via salt metathesis. These complexes have been characterized by 1H and 13C NMR spectroscopy. X-ray crystallography confirmed the bidentate nature of the HFDI ligand in (HFDI)Zr(NEt2)2(THF) as well as the eta-5-coordination of the indene moiety in (IDI)Zr(NEt2). The structures of analogous complexes (HFDI)Ti(NEt2)2 and (IDI)Nb(NtBu)(py) were determined by 1H and 13C NMR spectroscopy. Another eta-5-coordinated complex, (FDI)Zr(CH3) was characterized by NMR spectroscopy. This complex exhibits a methyl resonance indicative of transition metal-methyl complexes. These constrained geometry complexes serve as a representative sample for the preparation of various CGC's with this ligand framework. Chapter 3 also reports the initial preparation of titanium metal-imido complexes that feature di(3-methylindolyl)methane ligands with one neutral pendant donor. Three complexes, (tBuN)Ti{(2-py)di(3-methylindolyl)methane}, (tBuN)Ti{(N-methylimidazolyl)di(3-methylindolyl)methane}, and (tBuN)Ti{(2-MeOC6H4)di(3-methylindolyl)methane} were characterized by 1H and 13C NMR spectroscopy. X-ray crystallographic analysis of (tBuN)Ti{(2-py)di(3-methylindolyl)methane}, while incomplete, confirmed the connectivity of this complex. In chapter 4, the in situ generation of copper(I)-pyridine derivative complexes and their olefin binding properties are reported. The new complexes [(Me-nic)3Cu(NCCH3)]PF6 (Me-nic = methylnicotinate), [(3-MeOpy)3Cu(NCCH3)]PF6, and [(3-HOpy)3Cu(NCCH3)]PF6 have been generated in situ and characterized by 1H and 13C NMR spectroscopy. These complexes were examined for their affinity to bind ethylene, propylene, 1-hexene, and cis- and trans-3-hexene. Variable-temperature NMR spectra of these alkene complexes revealed a dynamic system with fast exchange between free and coordinated alkene at temperatures as low as -80 deg C. Using an extrapolation method, room temperature binding constants were determined for these alkene complexes. These copper(I) compounds exhibit binding constants for ethylene and propylene that are significantly lower than those of complexes featuring multidentate amine-based donor ligands. Furthermore, these complexes do not appear to bind 1-hexene, cis-3-hexene, or trans-3-hexene. Appendix 1 reports the synthesis and characterization of metallophosphinate complexes of aluminum and gallium. These complexes are believed to consist of a M2P2O4 (M = Al, Ga) ring structure, which was confirmed by X-ray crystallographic analysis of [Ph2AlO2PPh2]2. Specifically, the complexes [Ph2AlO2PPh2]2, [Ph2GaO2PPh2]2, [Ph2AlO2P(OPh)2]2, and [Ph2GaO2P(OPh)2]2 have been synthesized. Also reported in this appendix are reactions of triphenylaluminum and triphenylgallium with phosphonic acids. Products isolated in reactions with phosphonic acids were difficult to characterize due to their insoluble nature and amorphous morphology.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Developing methodologies to synthesize high-value products efficiently from simple substrates with control over the reactivity and selectivity is highly favored by the chemical industry. Employing assisted tandem catalysis, where serial reactions can be carried out in one pot, to achieve streamlined complex syntheses significantly reduces the number of steps and waste. Harnessing spatial and temporal control in catalysis enables approaches toward one-pot transformations and allows the integration of several catalytic processes. Ferrocene-based ligand-supported metal complexes represent a promising class of catalysts that can incorporate redox control over catalytic processes. We have developed a redox-controlled selective hydroamination reaction catalyzed by (thiolfan*)Zr(NEt2)2 (thiolfan*= 1, 1'-bis (2,4-di-tert-butyl-6-thiophenoxy)ferrocene). In situ switching of the catalyst's state during the reaction enables selectivity toward different substrates (Chapter 2).Incorporating the greenhouse gas CO2 into N-carboxyanhydrides (NCAs) followed by subsequent NCA utilization illustrates the possibility of integrating two synthetic steps in one vessel to afford a valuable material with possible CO2 recycling. To demonstrate the immense potential of integrating multi-step transformations in one pot, we developed a set of sustainable conditions for NCA synthesis (Chapter 3). Moreover, several metal catalysts supported by ferrocene-based ligands were found to catalyze NCA polymerization in the presence of a co-catalyst. To establish an integrated system composed of two incompatible processes, we aimed to compartmentalize the active reagents for each step. The structure of the ferrocene-based pro-ligand was modified for surface anchoring. Our efforts toward immobilizing ferrocene-supported metal catalysts onto conductive surfaces pave the way of achieving spatiotemporal control over the processes of NCA synthesis and polymerization (Chapter 4). In addition to the redox-switchable characteristic, ferrocene-based compounds provide a unique platform to support lanthanides and engender distinctive optical properties to them. We synthesized and characterized a series of ytterbium complexes displaying an ultra-narrow absorption in the ultraviolet-visible (UV-Vis) region. The extraordinarily narrow linewidth observed for (thiolfan)YbCl(THF) (thiolfan = 1,1'-bis(2,4-di-tert-butyl-6-thiomethylenephenoxy)ferrocene) allows us to investigate its applications toward magnetic field and liquid cell quantum sensing (Chapter 5).
