Book Description
Seven chapters summarize the current status of organometallic cluster chemistry from the viewpoints of synthesis, structure and bonding, ligand substitution reactions, ligand transformations, polyhedral rearrangement, cluster fragmentation reactions, and metal clusters as homogeneous catalysts. An eighth provides an extensive bibliography of reviews for the period from 1965 to 1988. Annotation copyrighted by Book News, Inc., Portland, OR

(Uncorrected OCR) Abstract of thesis entitled RUTHENIUM AND OSMIUM-NITROGEN MULITPLE BONDED COMPLEXES WITH CHELATING NITROGEN AND / OR OXYGEN ATOM DONOR LIGANDS: SYNTHESIS, STRUCTURES AND REACTIVITY STUDIES Submitted by Yip Ka Lai for the degree of Doctor of Philosophy at The University of Hong Kong in March 2005 The chemistry of late transition metal-nitrido complexes have been a growing interest especially for nitrido-ruthenium(VI) and -osmium(VI) metal complexes. However, the reactivity studies on those nitride complexes are sparse in the literature. As a result, the reactivities of nitridoruthenium(VI) complexes toward nucleophilic, electrophilic and oxidizing agents were studied. [Ru^CNXL^Cl] [H2L1 = 2,6-bis(2,2-diphenyl-2-hydroxyethyl)pyridine] underwent nitrogen atom transfer reaction with PPI13, PPhMe2 (dimethylphenylphosphine) and dppe [l,2-bis(diphenylphosphino)ethylene] to give [RuIII(HL1)(PPh3)Cl2], [Ru^XPPhMe^Cl] and [RuIII(L1)(dppe)Cl], respectively. In the presence of py or Hpz, the reaction of [Ru^^XL^Cl] gave [RuIII(L1)(py)2Cl] and [RuIII(L1)(Hpz)3]Cl as respective products. An unsymmetrical u-nitrido dinuclear ruthenium complex, [Ru^L^ChCu-N^u^L'XCsHioN^l], was formed upon reaction of [Ru^CNXL^Cl] with 2,6-dimethylaniline. Excess (Me30)BF4 reacted with [Ru^CNXL^Cl] to give a dinuclear u-OH complex, [Ru2(N)2(L1)2(OH)]PF6. For the analogous reaction with [n-Bu4N][MVI(NXL)] [L = L2 and L3; M = Os and Ru; H4L = l,2-dichloro-4,5-bis(2-hydroxybenzamido)benzene, H4L = l,2-bis(2-hydroxybenzamido)benzene], protonation at the auxiliary ligand occurred to give [M^CNXHL)] as product. Oxidation of [n-Bu4N][OsVI(N)(L2)] by PhI(OAc)2 produced [n-Bu4N][OsVI(N)(L202)] in 10% yield. Based on X-ray crystal analysis, the coordinated phenoxy moiety was converted to a benzoquinone moiety while the Os=N group remained intact. A synthetic route for preparing ruthenium pyridyl-amine complexes bearing chelating tertiary amine 'ligands was developed. At pH 1.0, the cyclic vo.
