Self assembly of group 11 complexes with 2-mercaptothiazoline : their syntheses and reactions
(1992)
A series of butterfly-like complexes, containing in their cores either copper or silver atoms, has been prepared by addition of a Lewis base (PPh3, AsPh3, or py, where Ph = C6H5, and py = pyridine) to the insoluble precipitate ...
Enzymes in organic synthesis
(1992)
The synthetic utilities of enzymes as catalysts for asymmetric synthesis have been explored in several aspects. Fructose-1,6-diphosphate aldolase from rabbit muscle and E. coli, rhamnulose-1-phosphate aldolase and ...
Use of hydrothermal methods for the synthesis of metal molybdates, copper carboxylates and molybdenum phosphates
(1990)
In this work, hydrothermal reactions were studied as a synthetic method in three systems: metal molybdates, copper carboxylates and molybdenum phosphates. Different solvents were used in each system studied to determine ...
The chemical generation of superoxide ion, and its relative reactivity (versus hydroperoxide ion and hydroxide ion) with halocarbons, esters, and nitriles in aprotic media
(1990)
With dioxygen-saturated (1 atm, 2.1 mM) dimethyl sulfoxide solutions that contain aniline (1-15 mM), the addition of excess hydroxide ion (10:1 HO-/PhNH2) yields approximately two superoxide ions (O2-), one azobenzene, and ...
In situ studies of adsorption of inorganic anions on metallic electrodes
(1992)
The adsorption of HSO4-, Cl- and I- from aqueous solutions was examined using radiotracer, FTIR spectroscopy and ellipsometry techniques. Adsorption dependence was measured as a function of time, concentration and potential. ...
Selective oxidation of olefins over transition metal-exchanged zeolite Y
(1979)
The selective oxidation of olefins including oxidative dehydrogenation and epoxidation reactions over transition metal-exchanged zeolite. Y at mild reaction conditions was investigated. This dissertation describes the ...
Molecular structures by theoretical means : applications to metal ion monohydrates, quadruply bonded dichromium(II) complexes, and carbonyl labilization in ligand substitution reactions
(1988)
Ab initio Hartree-Fock-Roothaan self-consistent-field (HFR-SCF) and generalized valence bond (GVB) geometry optimizations are used to study problems that are inaccessible to experiment. The theoretically determined molecular ...
The oxidative dehydrogenation of ethane : gas-phase and catalytic
(1988)
The gas-phase and the catalytic oxidative dehydrogenation of ethane were studied. Lithium-promoted magnesium oxide was investigated as the catalyst. In the gas-phase oxidation study a perfectly mixed tubular reactor was ...
Ziegler-Natta catalyzed polymerization kinetics : origin of the molecular weight distribution
(1986)
The molecular weight distributions generated by Ziegler-Natta catalyzed polymerizations are examined. Only those catalysts with one type of catalytic species are considered. From the rate laws for propagation and elimination, ...
