The Reductive Conversion of Some Cyclic and Acyclic vic-Epoxides to Alcohols by Means of Lithium Aluminium Hydride/Aluminium Trichloride
(Wiley, 1985)
Unsubstituted medium‐ring 1,2‐epoxycycloalkanes and certain vic‐epoxyalkanes are reduced to the corresponding alcohols very slowly when LiAlH4 alone is used as reducing agent. However, the combination of LiAlH4 and AlCl3, ...
Preliminary organic geochemical investigation of Upper-Jurassic dolomites of Plješvica (Yugoslavia)
(Elsevier, 1984)
The amounts and compositions of the total and soluble organic matter were determined in 17 samples of Upper Jurassic dolomites from the slopes of the mountain Plješivica (Lika, Yugoslavia; locations Vrelo-Mrsinj Grad, ...
Determination of low levels of cyanide with a silver/silver sulphide wire electrode
(Elsevier, 1987)
A silver/silver sulphide electrode is prepred quickly by holding a cleaned silver wire in vapours from molten sulphur. In 1000-10 mg l-1 cyanide solutions, the electrode exhibits a linear E/log CCN function which becomes ...
Structural effects in electrocatalysis
(Springer Science and Business Media LLC, 1982)
Studies of chemical reactions on well-defined surfaces provide fundamental data on surface reactivity and guidelines for the understanding and design of catalytic materials but few such studies have been done in electrocatalysis. ...
Anodic deposition of colloidal gold
(Elsevier, 1984)
Colloidal gold solutions were prepared following classical recipes. When electrolysed between graphite electrodes, gold was found to deposit at the anode. The rate of deposition was dependent on the anode potential, on the ...
The behaviour of mixed metal sulphide/silver suphide sensing materials in solutions of silver ions
(Analytica Chimica Acta, 1985)
Hydrophobized graphite electrodes activated with CuS/Ag2S can be used to measure silver ion activities as effectively as silver sulphide electrodes, whereas electrodes activatd with PbS/Ag2S or CdS/Ag2S are useless for ...
Configurations in unsymmetrically N-methyl-N-substituted 2-phenylacetamides
(Elsevier, 1986)
The syntheses of a various N-methyl-N-substituted 2-phenylacetamides of the general formula PhCH 2 CON(CH 3 )R, wherein, R is ethyl, n-propyl, isopropyl and t-butyl group, were performed. The 1 H n.m.r. spectra of these ...
Two‐dimensional NMR spectra of sesquiterpenes. I—NOESY study of caryophyllenes from Inula spiraeifolia
(John Wiley & Sons Ltd., 1987)
The application of two‐dimensional NOE NMR spectroscopy (NOESY) for the stereochemical assignment of isomeric 14‐acetoxy‐13‐hydroxy‐ and 13‐acetoxy‐14‐hydroxy‐5,6‐caryophyllen‐7‐ones, and their acetylation products, is ...
Multistage alkaline permanganate degradation of a type II kerogen
(Elsevier, 1984)
The products of a 27-step alkaline permanganate degradation of a type II kerogen from a sample of Toarcian shale, Paris Basin, have been studied. The high yield of oxidation products consisted of 1.86% neutrals and bases, ...
Mass-spectrometric analysis of the products formed in a D.C. Arc Plasma / Massenspektrometrische Analyse der im Gleichstrombogen-Plasma gebildeten Produkte
(Springer Nature, 1980)
The carbon content was determined in the plasma of horizontal electric arc discharging between carbon electrodes in a) a graphite tube and b) a ceramic tube, in the presence of an inhomogeneous magnetic field. After 20 s ...
