Available in PDF, EPUB and Kindle. Book excerpt: RuCl3(NO)(PPh3)2 reacts with two equivalents of Ph2PCH2P(O)Ph2 (dppmO) or Ph2P(CH2)2P(O)Ph2 (dppeO). In these reactions both triphenylphosphines on the ruthenium metal are replaced with ligands. RuCl3(NO)(dppmO)2 and RuCl3(NO)(dppeO)2 were characterized with IR and NMR spectroscopy, as well as x-ray crystallography. The complexes are octahedral with the two coordinated ligands trans to one another, displaying AA'XX' spin systems. Coupling constants and chemical shifts were determined by simulations using Spinworks. Both complexes can also be synthesized by heating two equivalents of ligand with one equivalent of RuCl3(NO)H2O. A chloride can be abstracted from RuCl3(NO)(dppmO)2 when reacted with AgBF4. NMR spectra indicate that the removal of a chloride allows the phosphoryl oxygen of the ligand to coordinate to the open site. A complex containing the same cation can be synthesized by reaction of a 2:1 molar ratio of dppmO and RuCl3(NO)H2O at room temperature. Both products have been characterized using IR and NMR spectroscopy, and x-ray crystallography in the case of the RuCl3(NO)H2O reaction. Crystals of [RuCl2(dppeO)2]+BF4- were obtained from the reaction of RuCl3(NO)(dppeO)2 and excess AgBF4. In this reaction NO+ is abstracted and Ru(II) is oxidized to Ru(III). Preliminary 31P data indicates that there are other products in this reaction. The differences in catalytic abilities of these complexes have yet to be determined.

Download or read book Ruthenium Chemistry written by Ajay Kumar Mishra and published by CRC Press. This book was released on 2018-01-17 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will describe Ruthenium complexes as chemotherapeutic agent specifically at tumor site. It has been the most challenging task in the area of cancer therapy. Nanoparticles are now emerging as the most effective alternative to traditional chemotherapeutic approach. Nanoparticles have been shown to be useful in this respect. However, in view of organ system complicacies, instead of using nanoparticles as a delivery tool, it will be more appropriate to synthesize a drug of nanoparticle size that can use blood transport mechanism to reach the tumor site and regress cancer. Due to less toxicity and effective bio-distribution, ruthenium (Ru) complexes are of much current interest. Additionally, lumiscent Ru-complexes can be synthesized in nanoparticle size and can be directly traced at tissue level. The book will contain the synthesis, characterization, and applications of various Ruthenium complexes as chemotherapeutic agents. The book will also cover the introduction to chemotherapy, classification of Ru- complexes with respect to their oxidation states and geometry, Ruthenium complexes of nano size: shape and binding- selectivity, binding of ruthenium complexes with DNA, DNA cleavage studies and cytotoxicity. The present book will be more beneficial to researchers, scientists and biomedical. Current book will empower specially to younger generation to create a new world of ruthenium chemistry in material science as well as in medicines. This book will be also beneficial to national/international research laboratories, and academia with interest in the area of coordination chemistry more especially to the Ruthenium compounds and its applications.

This book was released on 1990 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: The products and mechanisms of the thermal reactions of several complexes of the general structure (PMe3)4Ru(X)(Y) and (DMPM)2Ru(X)(Y) where X and Y are hydride, aryl, and benzyl groups, have been investigated. The mechanism of decomposition depends critically on the structure of the complex and the medium in which the thermolysis is carried out. The alkyl hydride complexes are do not react with alkane solvent, but undergo C-H activation processes with aromatic solvents by several different mechanisms. Thermolysis of (PMe3)4Ru(Ph)(Me) or (PMe3)4Ru(Ph)2 leads to the ruthenium benzyne complex (PMe3)4Ru([eta]2-C6H4) (1) by a mechanism which involves reversible dissociation of phosphine. In many ways its chemistry is analogous to that of early rather than late organo transition metal complexes. The synthesis, structure, variable temperature NMR spectroscopy and reactivity of ruthenium complexes containing aryloxide or arylamide ligands are reported. These complexes undergo cleavage of a P-C bond in coordinated trimethylphosphine, insertion of CO and CO2 and hydrogenolysis. Mechanistic studies on these reactions are described. The generation of a series of reactive ruthenium complexes of the general formula (PMe3)4Ru(R)(enolate) is reported. Most of these enolates have been shown to bind to the ruthenium center through the oxygen atom. Two of the enolate complexes 8 and 9 exist in equilibrium between the O- and C-bound forms. The reactions of these compounds are reported, including reactions to form oxygen-containing metallacycles. The structure and reactivity of these ruthenium metallacycles is reported, including their thermal chemistry and reactivity toward protic acids, electrophiles, carbon monoxide, hydrogen and trimethylsilane. 243 refs., 10 tabs.

This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of the halide ligand on the fluorescence lifetime of a series of Ru(II) complexes, tcc-RuX2(POC4Pyr-P, O)2 (X = Cl (3), Br (4), I (5)) containing the hemilabile phosphine ether ligand 4-{2-(diphenylphosphino)phenoxy}butylpyrene (POC4Pyr (1)), is reported. The synthesis and characterization of both the ligand, POC4Pyr (1), and ligand oxide, P(=O)OC4Pyr (2), and the solid-state structure of 1 are also presented. New complexes based on a similar framework incorporating phosphine pyrenyl imine and phosphine pyrenyl amine ligands and a palladium metal center, PdCl2(PNPyr-P, N) (14) (PNPyr = 2-diphenylphosphino-N-(1-pyrenyl)benzylidineimine (12)) and PdCl2(PNHPyr-P, N) (15) (PNHPyr = 2-diphenylphosphino-N-(1-pyrenyl)benzylidineamine (13)), are presented . The UV-vis, steady-state fluorescence, and solid state structures of 14 and 15 are presented. The synthesis and characterization, as well as the solid state structures of both ligands, 12 and 13, are also presented. Preliminary steady-state fluorescence experiments provide promising results for a potential "OFF-ON" or "ON-OFF" chemosensor. However, initial reactivity of the palladium complexes with carbon monoxide and sulfur dioxide were unsuccessful; further experiments are needed to optimize the reactivity of these complexes.

Available in PDF, EPUB and Kindle. Book excerpt: Over the last 60 years the increasing knowledge of transition metal chemistry has resulted in an enormous advance of homogeneous catalysis as an essential tool in both academic and industrial fields. Remarkably, phosphorus(III) donor ligands have played an important role in several of the acknowledged catalytic reactions. The positive effects of phosphine ligands in transition metal homogeneous catalysis have contributed largely to the evolution of the field into an indispensable tool in organic synthesis and the industrial production of chemicals. This book aims to address the design and synthesis of a comprehensive compilation of P(III) ligands for homogeneous catalysis. It not only focuses on the well-known traditional ligands that have been explored by catalysis researchers, but also includes promising ligand types that have traditionally been ignored mainly because of their challenging synthesis. Topics covered include ligand effects in homogeneous catalysis and rational catalyst design, P-stereogenic ligands, calixarenes, supramolecular approaches, solid phase synthesis, biological approaches, and solubility and separation. Ligand families covered in this book include phosphine, diphosphine, phosphite, diphosphite, phosphoramidite, phosphonite, phosphinite, phosphole, phosphinine, phosphinidenene, phosphaalkenes, phosphaalkynes, P-chiral ligands, and cage ligands. Each ligand class is accompanied by detailed and reliable synthetic procedures. Often the rate limiting step in the application of ligands in catalysis is the synthesis of the ligands themselves, which can often be very challenging and time consuming. This book will provide helpful advice as to the accessibility of ligands as well as their synthesis, thereby allowing researchers to make a more informed choice. Phosphorus(III) Ligands in Homogeneous Catalysis: Design and Synthesis is an essential overview of this important class of catalysts for academic and industrial researchers working in catalyst development, organometallic and synthetic chemistry.
