Synthesis and characterization of sulfur-capped trinuclear molybdenum and tungsten clusters
(1992)
The synthesis of molybdenum and tungsten trinuclear clusters is presented. The clusters of interest contain a M3(μ3-S)(μ2-S2)3[^4+] core with nine terminal ligands, i. e. three bound to each metal center. The ligands ...
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 ...
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. ...
Syntheses of linear tetrapyrroles as potential inhibitors for uroporphyrinogen III synthase
(1992)
Living systems depend on a variety of metal complexes of tetrapyrrolic macrocycles to carry out many biologically important functions. Among these pigments of life are heme, chlorophyll and vitamin B[12]- All these substances ...
Enzyme catalyzed oxido-reductive reactions : synthetic applications and mechanistic studies
(1992)
Chapter II describes the synthetic application of a non-heme monooxygenase from Pseudomonas oleovorans (POM) toward the preparation of a series of epoxides from their protected allylic alcohol precursors. Like other ...
Discovery of a labile nickel ion required for CO/acetyl-CoA exchange activity in the NiFe complex of carbon monoxide dehydrogenase
(1992)
The oxygen-sensitive, nickel and iron-containing enzyme carbon monoxide dehydrogenase (CODH) from clostridium thermoaceticum was purified without any significant loss of the activity present in the crude extract. The careful ...
Surface modification of polyolefins using new synthetic techniques
(1992)
A new technique for functionalization of polyolefin surfaces using C-H bond activation catalysts has been developed. The Gif system which was developed by the Barton group as a model of methane monooxygenase has been ...
Surface electrochemical studies of iodine adlattices on Pd(111) and Pd(100) single-crystal electrodes
(1992)
The structure, composition and electrochemical reactivity of iodine adsorbed from aqueous iodide solutions onto Pd(111) and Pd(100) single-crystal electrodes have been investigated. Characterization of the I/Pd system ...
Vibrational spectroscopic studies of adsorbates on bimetallic surfaces
(1992)
In this work, well-defined bimetallic surfaces have been studied using carbon monoxide adsorption in conjunction with infrared reflection absorption spectroscopy (IRAS). These studies have indicated that for CO adsorbed ...
