Book Synopsis Development of Nickel(II) Complexes of Oxime Containing Ligands for the Activation of Dioxygen by : Michael Joseph Goldcamp

This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Ligands containing two oxime donor groups with a variable third group in a tripodal amine motif have been designed and synthesized. Their Ni(II) complexes, and some Zn(II), Cu(II), and Fe(III) complexes, have been structurally and spectroscopically characterized. Deprotonation of the oxime groups gives Ni(II)--Polyoximate complexes that form bis(N-O) oximate bridged dimers with significantly low oxidation potentials for Ni(II). These Ni(II)-polyoximate complexes react with dioxygen, consuming multiple equivalents. This is unusual chemistry for Ni(II), especially in the absence of ligand oxidation. The Ni(II) / O 2 reaction system promotes oxidation of triphenyl phosphine, with oxygen atom transfer, benzyl alcohol, and 3,5-di-tert-butylcatechol. Reaction of the Ni(II)-polyoximate complexes with o-quinones causes the formation of high-valent nickel complexes of the reduced dioxolenes, semiquinones and catecholates.

Book Synopsis Chiral and Achiral Copper(II) and Nickel(II) Complexes with Novel Multidentate Ligands by : Molly A. O'Connor

This book was released on 2013 with total page 812 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bidentate, tetradentate, and hexadentate ligands, with N2, N4, and S2N4 donor sets were complexed with Cu(II) and Ni(II) to form chiral and achiral chelates in an attempt to prepare complexes that allowed for the access of multiple oxidation states through electrochemical methods. The bidentate ligands were prepared from pyrrole-2-carboxaldehyde and chiral and achiral amines and anilines, and were complexed with the desired metal in a 2:1 ratio, with chiral ligands resulting in chiral complexes. Analogous ligands with N4 coordination spheres were also prepared using pyrrole-2-carboxaldyhyde and various diamines, and were complexed in a 1:1 fashion. The tetradentate ligands were prepared using vinylpyridine and chiral piperazine derivatives to form both enantiomers of the chiral complexes, as well as similar non-chiral mono and dinuclear complexes using achiral derivatives of piperazine and homopiperazine. The hexadentate ligands were synthesized from 2-hydrazinopyridine and alkyl and aryl bridged dithio-diketo precursors, which were prepared using either a N,N,N-triethyl-N-(propan-2-onyl)ammonium or N,N,N-triethyl-N-(phenylethan-2-onyl)ammonium chloride salt and a range of dithiols. Synthetic, crystallographic, and absorption data will be presented as well as circular dichroism (CD) data for the chiral complexes and magnetic data for the dinuclear complex. Complexes were also characterized using electrochemistry and ESR.

This book was released on 2015 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ni(II) pincer complexes are among the most important and useful compounds in homogeneous catalysis. Significant advancement has been made in this field in recent years. Many Ni(II) pincer complexes have been prepared and utilized in various catalytic reactions e.g. cross coupling reactions, C-H activation, carbon dioxide activation etc. Still, nickel(II) complexes supported by the pincer ligand with three nitrogen donors are relatively less explored and catalytic applications with those complexes are scarce in literature. This thesis describes the synthesis of a new pyrrolyl pyridine based pincer ligand and its Ni(II) complexes. The pyrrolyl pyridine pincer ligand, a relatively new class of dianionic, tridentate, nitrogen-based ligands in coordination chemistry, was prepared starting with a modified method for the synthesis of pyrrolyl pyridine. This modified procedure is simpler, less time consuming making it cheaper than the classical method and provides 2,6-bis(3,5-ditolyl-2-pyrrolyl)pyridine in good yields. Reaction of its potassium salt with Ni(OTf)2 resulted in three different stable nickel(II) pincer complexes. The novel nickel(II) pincer complexes were fully characterized by 1H NMR spectroscopy, 13C NMR spectroscopy, infrared spectroscopy and high resolution mass spectrometry. The X-ray crystal structures of the new ligand and metal complexes have been described.

Available in PDF, EPUB and Kindle. Book excerpt: An investigation was undertaken of the coordinating properties of flexible tetradentate phosphorus, arsenic, and nitrogen ligands of the type D(CH2CH2CH2D')3, (where D does not = D'). A series of nickel (II) complexes with the five coordinate (Ni(ligand)X)(+) cations was isolated and studied extensively. A number of Pd(II) and Co(II) complexes were also examined. A second series of studies involved the nature of bonding in boron-transition metal complexes having groups of the type B(OCH2CH2NR2). Also, the synthesis of a number of tetradentate compounds with boron-carbon bonds was undertaken (e.g., B(Ph-AsO2)3).
