Remote functionalisation by ferrous ion-cupric ion induced decomposition of alkyl hydroperoxides
(Pergamon Press, 1979)
By decomposition of alkyl hydroperoxides 1-8 with ferrous sulfate-cupric acetate reagent, intramolecular functionalisation of remote non-activated C atom takes place and unsaturated alcohols with double bond mainly at ...
Electrocatalysis by foreign metal monolayers: Oxidation of formic acid on platinum
(Elsevier, 1975)
It was demonstrated that some foreign metal monolayers formed by underpotential deposition have pronounced catalytic effects on the oxidation of formic acid on platinum. The explanation of these effects was sought within ...
Quercetagetin 6,7,3',4'-tetramethyl ether: a new flavonol from Artemisia annua
(Elsevier, 1975)
Plant: Artemisia annua L. Source: South of Belgrade. A CHCl, extract of the whole plant yielded after chromatography a new polar flavonol, yellow crystals, mp 171-172 degrees, M+ m/e 374, C19H18O8. characterized by UV/VIS, ...
The polarographic and chronopotentiometric investigation of the copper(II)-ethylenedithioldiacetic acid system
(Elsevier, 1975)
The electrode process of the Cu(II)-ethylenedithioldiacetic acid chelatereduction occurs in two one-electron reduction steps. The reversibility of the first polarographic wave was confirmed by microcoulometry at constant ...
An analysis of elementary processes of water desorption from zeolites of type aPart. I. Zeolites with monovalent counterions: undefined
(Elsevier, 1976)
Complex DSC curves of water desorption from LiA, NaA and KA zeolites were resolved into the most probable elementary curves. The activation energies and transition temperatures of corresponding elementary processes were ...
Catalytic effects of monolayers of metals deposited at underpotentials: Oxidation of formic acid on platinum
(Elsevier, 1975)
It was recently shown that the monolayers of some metals deposited at underpotentials
on gold can substantially increase the rates of some redox reactions 1 , and the
rate of oxygen reduction:. This note reports the ...
Extractives of Artemisia scoparia
(Elsevier, 1973)
Artemisia scoparia collected south of Belgrade was used. Capillin, 1-phenyl-2,4-hexa-diyne-1-ol, vanillin, and scoparone were isolated. All compounds were identified by direct comparison with authentic materials, by m.m.p., ...
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 dissolution of iron under cathodic polarization
(Pergamon Press, 1979)
It has been shown that the dissolution rate for iron at cathodic potential is higher than expected on the grounds of the Wagner-Traud mixed potential theory. This observation cannot be explained by a parallel chemical ...
