The reaction of lead tetra-acetate with some unbranched α,ω-diols
(Elsevier, 1969)
Unbranched α,ω-diols are mainly converted by means of lead tetra-acetate in refluxing benzene to the corresponding ethers of di-α-tetrahydrofuryl, di-α-tetrahydropyryl and/or α-tetrahydrofuryl-α′-tetrahydropyryl type. Thus, ...
New Methods of Obtaining Fuel Cell Electrodes: IV . Powder Electrode Fuel Cell with Lateral Feeding
(USA : American Chemical Society, 1969)
A previously developed powder electrode in combination with lateral feeding with gases has been further improved. A fuel cell without gas chambers and with loose carbon powder electrodes has been constructed and tested ...
Reactions with lead tetraacetate-I. Oxidation of saturated aliphatic alcohols part 1
(Elsevier, 1964)
When oxidized with lead tetraacetate 1-heptanol and 1-octanol undergo cyclization to give as major products the corresponding 2-alkyltetrahydrofurans, accompanied by a small amount of the isomeric tetrahydropyran derivatives. ...
Lead tetraacetate oxidation of saturated aliphatic alcohols-IV. The formation of six-membered cyclic ethers
(Elsevier, 1965)
The lead tetraacetate oxidation of saturated aliphatic alcohols, with structures which do not permit 1,5-cyclization, gave tetrahydropyran derivatives in yields not exceeding 16%. The formation of a small amount of the ...
Reactions with lead tetraacetate-IV. Oxidation of saturated aliphatic alcohols-II; Alcohols of low molecular weight
(Elsevier, 1965)
The action of lead tetraacetate on ethanol, 1-propanol, 2-propanol and 2-butanol has been studied under various experimental conditions, and it was found that the tetravalent lead compound reacts with alcohols in ways not ...
Opening of steroid ring a by means of lead tetraacetate
(Elsevier, 1964)
The lead tetraacetate oxidation of cholestan-1β-ol and cholestan-1α-ol in benzene solution did not afford cyclic ethers but resulted, in major part, in the opening of ring A with formation of 1,10-seco-aldehydes. In addition, ...
Investigation of active carbon for fuel-cell electrodes
(Elsevier, 1969)
The influence of grain size, mode of catalyst impregnation, and different surface treatments on the electrochemical activity of active carbon for hydrogen fuel-cell electrodes was studied. The experiments were done in a ...
The conversion of unbranched primary alkyl and arylalkyl amines to nitriles by means of lead tetraacetate
(Elsevier, 1965)
The only amino compounds oxidized so far with lead tetroacetate were primary aromatic amines, which gave mainly the corresponding azo compounds(1), and some tertiary aryldialkyl amines, which in glacial acetic acid in the ...
A proposal for use of "Tandel" to obtain optimal temperature of electro-optical devices
(Elsevier, 1966)
A proposal is given for the use of Tandel to obtain the desirable temperature of ferroelectric crystal and optimal working temperature of electro-optical devices as well. The variation of ∈ due to temperature inhomogeneity ...
Configuration and reactivity of ten-membered 5,10-seco-compounds obtained by fragmentation of 5-hydroxy-steroids
(Elsevier, 1966)
Assignment of configuration to the 1,10-double bond in the cis-trans isomeric 3β-acetoxy-5,10-seco-1,10-cholesten-5-ones has been achieved by means of NMR spectrometry. Some reactions of these new compounds have been studied ...
