New approach to the aromatization of ring B in 19-norsteroids and to the synthesis of equilenin-type compounds
(Royal Society of Chemistry, 1978)
When 7α-acetoxy-3,3 : 17,17-bis(ethylenedioxy)-5,10-epoxy-5β, 10β-oestran-6-one (2), formed by lead tetra-acetate acetoxylation of the parent compound (1), is heated with alkali, it undergoes ring B aromatization to give ...
Investigation of occluded and nonoccluded synthetic zeolites. Base-catalyzed demethylation of tetramethylthionine-methylene blue on a denitrated zeolite
(Elsevier, 1972)
The adsorption of methylene blue from aqueous and non-aqueous media onto the zeolite NaA, the occluded zeolite NaANaNO3 and the denitrated zeolite NaANa2O has been investigated. Adsorption isotherms have a standard form ...
Effect of codeposition of polymer on the morphology of electrodeposited copper
(Kluwer Academic Publishers, 1979)
Poly(4-vinyl pyridine-co-methyl methacrylate), which is soluble in water in its protonated form and insoluble as a neutral molecule, has been synthesized and introduced into an acid bath for copper deposition. Potential-sweep ...
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 ...
Direct solution analysis using an arc source incorporating two plasmas rotating in a graphite tube
(Elsevier, 1977)
As a continuation of earlier work on arc sources for the spectrochemical analysis of powdered samples, a source appropriate for multi-element analysis of trace elements in solution has been developed. The nebulized solution ...
Acetoxylation of steroidal lactones by means of lead tetraacetate
(Elsevier, 1970)
One of the structural features of many bitter principles ls the presence of a &-lactone ring. Some of these compounds differ from one another by the state of oxidation of the molecule as a whole and also by the state of ...
Electrocatalysis on Surfaces Modified by Foreign Metal Adatoms
(WILEY‐VCH, 1979)
An approach to the problem of electrocatalysis, which consists of modification of electrode surfaces by foreign metal adatoms, is presented. The paper reviews the work done in the author's lab on the effects of foreign ...
Cohesive energy densities of poly(di‐n‐alkyl itaconates)
(Wiley, 1977)
The solubility parameters of the first ten members of the homologous series of poly(di‐n‐alkyl itaconates) were determined from limiting viscosity numbers in various organic solvents, differing in structure, polarity and ...
The Electric Conductivity of Molten HgI2-HgBr2 and HgI2-SbI3 Binary Mixtures
(De Gruyter, 1975)
The specific electric conductivity of molten HgI2-HgBr2 and HgI2-SbI3 binary mixtures was measured as a function of composition and temperature in the ranges 220 — 540 °C and 180 to 540 °C, respectively. In the HgI2-HgBr2 ...
