Control of intramolecular γ-alkylation vs. α-alkylation of an αβ-unsaturated ketone: An unusual solvent effect
(Royal Society of Chemistry, 1979)
Most base-solvent combinations convert (2) into (3); γ-alkylation to yield (5) is effected by sodium hydroxide in dimethyl sulphoxide-water mixtures in which the water content is critical.
A new technique for measuring adsorption on non-noble metals
(Elsevier, 1974)
A new technique for measuring adsorption on non-noble metals is presented here on the basis of former experimental results and experience.
Electrocatalysis by foreign metal monolayers. Oxidation of formic acid on palladium
(Elsevier, 1978)
Catalytic effects of foreign metal monolayers deposited at underpotentials have been found for the oxidation of formic acid on palladium electrode. Palladium is known to form no poisoning species in oxidation of HCOOH. ...
On the kinetics and mechanism of the Cd(II)/Cd(Hg) system in acid media
(Elsevier, 1977)
The kinetics and mechanism have been investigated in the Cd(II)/Cd(Hg) system in 2 M NaClO4 + 1 M HClO4, at 25 ± 0.5°C. The galvanostatic single-pulse method has been used. The value of double-layer capacity, exchange ...
Inhibitory effects of manganeous, cadmium and zinc ions on hydrogen evolution reaction and corrosion of iron in sulphuric acid solutions
(Pergamon Press, 1978)
The presence of metal ions (Cd2+, Mn2+, Zn2+), more electronegative than the cathodic potential for the hydrogen evolution reaction on iron in a 0.25M H2SO4 solution, inhibits the hydrogen evolution reaction and corrosion ...
Intramolecular cyclization of 3β-acetoxy-16-picolinylidene-5-androsten-17-one by catalytic hydrogenation
(Elsevier, 1970)
Intramolecular cyclization by catalytic hydrogenation of 3β-acetoxy-16-picolinylidene-5-androsten-17-one (IV) (80° and 50-60 atm of hydrogen pressure over Pd/C as catalyst) gives rise to the formation of two cyclic products, ...
The Reduction of Some 1, 2‐Epoxides with Lithium Aluminium Hydride. Preliminary Communication
(Wiley - VCH Verlag GmbH & Co, 1976)
The factors influencing the ease of the lithium aluminium hydride reduction of various 1,2‐epoxycycloalkanes and 1,2‐epoxyalkanes are described and discussed.
The lead tetraacetate reaction of alcohols containing a small ring. Part II. Cyclobutane‐methanols and cyclopropane‐ethanols
(Wiley, 1976)
The leadtetraacetate and lead tetraacetate/metal chloride oxidations of cyclobutane‐methanol, cyclopropane‐ethanol and the corresponding α, α‐diniethyl alcohols have been investigated and compared with the oxidative reactions ...
The possibility of separating hydrogen fluoride from its gaseous mixture with silicon tetrafluoride
(Elsevier, 1973)
We report in this paper investigations of the conditions necessary to effect the selective absorption of hydrogen fluoride from its gaseous mixture with silicon tetrafluoride when that mixture is brought into contact with ...
Carbon-air electrode with regenerative short time overload capacity: Part 1. Effect of manganese dioxide
(Springer Nature, 1973)
To increase the overload capacity of the carbon-air electrode in alkaline electrolyte, without seriously changing the electrode potential during short-time overload periods, small amounts of MnO2 were added to carbon and ...
