Stereospecific synthesis of [gamma]-butyrolactones from acyclic vinyl sulfoxides: an asymmetric synthesis of optically pure oak lactones
(Elsevier, 1985)
The sulfoxide-directed lactonization of several trisubstituted vinyl sulfoxides with dichloroketene proceeds in a completely stereospecific manner. The lactonization of (E) -3 (R) --tolylsulfinyloctene occurs with complete ...
Fischer-Tropsch synthesis on bimetallic ruthenium-gold catalysts
(Elsevier, 1985-06)
The effect of Au in the behavior of Ru as a Fischer-Tropsch catalyst was studied. Two series of catalysts were investigated, one supported on SiO2 and the other on MgO. Au did not seem to alter the product distribution on ...
The molecular and crystal structure of pentacarbonyl(phosphabenzene)molybdenum(0)
(Elsevier, 1985-03-05)
Pentacarbonyl(phosphabenzene)molybdenum(0) crystallizes in the Pbam space group with Z = 8, a 15.880(4), b 20.162(4) and c 7.971(3) A. The crystal structure was determined and refined from 1404 independent reflections to ...
Molybdena on titania : I. Preparation and characterization by Raman and Fourier Transform Infrared spectroscopy
(Elsevier, 1985-04)
Titania-supported molybdenum and cobalt-molybdenum catalysts were prepared by the dry impregnation and equilibrium adsorption techniques. Raman and Fourier Transform Infrared spectroscopy were used to follow the changes ...
Influence of chlorine on the surface area and morphology of TiO2
(Elsevier, 1985)
Changes in BET surface area and morphology of TiO2 (anatase) were studied as a function of temperature and level of chlorine contamination. The obj
CO hydrogenation catalyzed by alumina-supported osmium: Particle size effects
(Elsevier, 1985-10)
Alumina-supported catalysts were prepared by conventional aqueous impregnation with [H2OsCl6] and by reaction of organoosmium clusters {[Os3(CO)12], [H4Os4(CO)12], and [Os6(CO)18]} with the support. The catalysts were ...
Metal dispersion of bimetallic catalysts via stepwise chemisorption and surface titration : I. Ru---Au/SiO2
(Elsevier, 1985-09)
A stepwise chemisorption and titration procedure involving H2 and O2 as adsorbates is used to measure the dispersion of the individual metal components in bimetallic Ru---Au/SiO2 catalysts. The experimental approach is ...
