La Constante D'Acidité de L'ion Anilinium Dans le Formamide
Authors: Mandel M. , Decroly P. 
Published: September 2010

AbstractThe dissociation constant ka of the anilinium ion in formamide has been determined at several temperatures between 20 and 45°C by two independent methods. The spectrophotometric determination of ka and the potentiometric method using a cell without transference gave results which are in good agreement except at 45°C, although the measurements are difficult due to a secondary transamination reaction between the anilinium ion and formamide. This agreement give additional confirmation to the standard potentials of the Ag; AgCl reference electrodes in formamide as previously determined for the temperature range of 20 to 40°C. Furthermore ka of anilinium ion appears to be a factor four larger in formamide than in water. The slope of the linear plot of ka against T−1 is nearly identical in both solvents.

AbstractL'oxamide, la malonamide et la fumaramide subissent l'hydrolyse en milieu alcalin, suivant le schéma classique: la diamide engendre l'acide amique (VI) qui se transforme ensuite en diacide correspondant (VII). Les auteurs en ont fait l'étude cinétique et déterminé les paramètres suivants (valeurs de k à 65°C):pour l'oxamidek = 1,2 10−1 1 m−1 s−1; ΔH≠ = 9,3 Kcal m−1; ΔS≠ = − 37,5 u.e.s.k = 2,1 10−3 1 m−1 s−1; ΔH≠ = 11 Kcal m−1; ΔS≠ = − 40,6 u.e.s.pour la malonamidek = 1,6 10−2 1 m−1 s−1; ΔH≠ = 16,0 Kcal m−1; ΔS≠ = − 21,6 u.e.s.k = 3,1 10−4 1 m−1 s−1; ΔH≠ = 11,4 Kcal m−1; ΔS≠ = − 43 u.e.s.pour la fumaramidek = 8,3 10−3 1 m−1 s−1; ΔH≠ = 15,5 Kcal m−1; ΔS≠ = − 24,4 u.e.s.k = 1,2 10−3 1 m−1 s−1; ΔH≠ = 10,3 Kcal m−1; ΔS≠ = − 43,6 u.e.s.L'hydrolyse de la maléamide est plus complexe; elle se déroule en trois étapes consécutives compétitives : la cyclisation de la diamide en imide (VI), l'ouverture du cycle en acide amique (VII) et enfin la transformation de I'acide amique en diacide (VIII), d'aprés les lois suivantes:VI = k [diamide] [OH−]VII = k [imide] [OH−] + k [imide] [OH−]2VIII = k [acide amique] [OH−]les paramètres correspondants (valeurs de k à 65°C) sont:k = 5,4 10−1 1 m−1 s−1; ΔH≠ = 6,4 Kcal m−1; ΔS≠ = − 43 u.e.s.k = 490 1 m−1 s−1; ΔH≠ = 13,4 Kcal m−1; ΔS≠ = − 8,8 u.e.s.k = 3,2 10−3 1 m−2 s−1; ΔH≠ = 18,7 Kcal m−1; ΔS≠ = + 24,2 u.e.s.k = 2,15 10−4 1 m−1 s−1; ΔH≠ = 18 Kcal m−1; ΔS≠ = − 24,2 u.e.s.
Mean Amplitudes of Vibration of some Tetrahedral XY4 Type Molecules Part VIII: Silicon tetrahalides
Authors: Nagarajan G. 
Published: September 2010

AbstractWith the recent vibrational and molecular structural data for silicon tetrahalides possessing a tetrahedral symmetry the computed numerical values of mean‐square amplitude quantities, generalized mean‐square amplitude quantities (mean‐square parallel amplitudes, mean‐square perpendicular amplitudes and mean cross products) and mean amplitudes of vibration at the temperatures T=0 and T=298°K have been reported. The paper deals with the relevant discussion over the arrived results. The Bastiansen‐Morino shrinkage effects at these temperatures have been calculated. All the calculations were made by the Cyvin's method using symmetry coordinates. The molar thermodynamic functions have also been calculated for these molecules except silicon tetrafluoride on the basis of a rigid rotator, harmonic oscillator model for the temperature range 50‐2000°K.

Étude du Comportement D'Isomères Géométriques Sous L'Impact Électronique IV. Cyclopropane, méthylcyclopropane et diméthylcyclopropanes gem, cis et trans
Authors: Natalis P. , Laune J. 
Published: September 2010

AbstractMass spectra of cyclopropane, methylcyclopropane, 1,1‐dimethylcyclopropane, cis‐1,2‐ and trans‐1,2‐dimethylcyclopropane have been recorded in the electron energy range 50‐10 volts, especially in order to study the effect of isomerism in the three dimethyl compounds.Surprisingly, only a slight effect of position isomerism shows up in 1,1 and 1,2 isomers and no effect of geometrical isomerism can be detected in cis and trans stereoisomers, contrarily to the published data. The identity of behavior of cis and trans isomers under electron impact seems to be related to the pseudoethylenic character of C‐C bonds in C3 ring which, in the present case, overcomes the expected steric effect observed in larger cyclanic isomers.Ionization potential of the three isomers and appearance potentials of main fragment ions are found to be the same within experimental uncertainties. Metastable transitions in the three isomers being identical, corresponding types of fragmentation are also the same. Fragment ions have therefore to be produced by a common molecular ion whose most probable structure is an isopentanic chain magnified image. Fragility of C‐C bonds close to substituting alkyl groups in branched hydrocarbons is confirmed by the present study of methylcyclopropane and gem‐dimethylcyclopropane.

Published: September 2010

AbstractVoacarpine, a minor alkaloid obtained from Voacanga chalotiana Pierre ex Stapf (Apocynaceae), is shown to have the tautomeric structure VII ⇆ VIII. The non basic O,N‐diacetyl‐ and O,N‐ditosyl derivatives are true 2‐acyl‐indoles (IX, X).Isovoacarpine, isomeric with voacarpine, is obtained by acid treatment followed by neutralization; it is also a carbinolamine compound. On acetylation, it gives a monoacetyl derivative.UV, IR, NMR and mass spectra of voacarpine and derivatives are discussed.
Mean Amplitudes of Vibration, Thermodynamic Functions, and Molecular Polarizabilities of Some Monohaloacetylenes
Authors: Nagarajan G. , Hariharan T. A. 
Published: September 2010

AbstractA brief survey of the vibrational and structural data for the monohalo‐acetylenes and their deuterated compounds except the higher member of the series possessing a linear asymmetrical structure with the point group C∞ν is given. The symmetry coordinates, G matrix elements and analytical expression for the mean‐square amplitudes of vibration have been given. The mean amplitudes of vibration at the room temperature have been calculated by the Cyvin's method. A brief discussion of the results follows. The molar thermodynamic functions have been calculated on the basis of a rigid rotator, harmonic oscillator model for the temperature range 100‐2000° K. Molecular polarizabilities have been calculated from a semi‐empirical delta‐function model by using a variational method and delta‐function electronic wave functions. The model enables one to obtain very simple expressions for the parallel and perpendicular components and mean molecular polarizabilities. A comparison of the observed and computed molecular polarizabilities shows that a deviation of nearly 10% is quite reasonable.
Electron Irradiation of Hydrocarbons. III. Radical Reactions and Diffusion During Radiolysis
Authors: Claes P. , Rzad S. 
Published: September 2010

AbstractThis work concerns the theoretical study of the influence of tracks expansion on radicals reactions occuring during the radiolysis of hydrocarbons. It is shown that a dose rate effect may occur on the organic products yields. This should be due to the competition between organic radicals recombination and hydrogen abstraction from the solvent by these radicals. Hydrogen atoms, however, react chiefly by hydrogen abstraction from the solvent.

Published: September 2010

AbstractThe polarographical behaviour of Mo (VI) in a supporting electrolyte composed of citric acid, potassium dihydrogen orthophosphate and potassium chloride was investigated.At pH 1, 6, Mo (VI) gives two waves with half‐wave electric tensions of ‐0,17 V and — 0,57 V vs S.C.E.The quantitative determination is based on the height of the second reduction wave which is proportional to the concentration of Mo (VI). Rounded maxima which appeared in certain cases are eliminated by addition of methylene blue or basic fuchsin.Cu (II), Bi (III), Pb (II), Zn (II), As (V), W, V, Ni (II), Co (II), Mn (II) and Zr (IV) do not interfere.Fe (III), when present in great quantity, must be eliminated. The wave of Cd (II) interfere.The method proposed was applied to the determination of Mo (VI) in steel samples.

AbstractMethane sulphonyl chloride, thionyl chloride and p‐toluene sulphonyl chloride react with voachalotine (I) to give, in each case, the same cyclised dihydroindole compound: 2α‐hydroxy‐17‐desoxyvincamajine(VI).At room temperature the same reagents give with affinisine (II) the expected derivatives, but at 115° only one compound is obtained: 16B‐chloromethyl‐voachalotane (VII).These observations are discussed on the basis of known reaction mechanisms and of the structure of the two alkaloïds (I and II), used in this work.
Dégradation de L'Acide Ribonucléique Microsomal par les Ultrasons
Authors: Burnotte J. , Fredericq E. 
Published: September 2010

AbstractThe action of sonic radiations (20 Kc) on RNA solutions has been studied in relation with structural characterizations. Ribosomal RNA from calf thymus was used; it had two components with molecular weights 1.3.106 and 0.5.106. The content of helical parts was estimated from hypochromic effect as 56%.Several sonicates were prepared using times of sonication from 2 minutes to 6 hours. Their intrinsic viscosities and sedimentation constants were determined. The minimum molecular weight which could be obtained was 60,000. Optical rotation and ultraviolet absorbancy of native and sonicated RNA samples were the same, indicating that the secondary structure was not modified by sonication. The influence of pH and dilution on absorbancy was also the same for all samples.The variation of viscosity with ionic strength was used as a means for estimating the flexibility of the molecules. These determinations showed that the sonicated RNA has a smaller degree of flexibility than the undegraded sample.It was concluded that by sonication the polynucleotide chains of RNA molecules are split mostly in the disordered regions.

Recherches sur L'Hétérocyclisation. III. Mécanisme de L'Hétérocyclisation des O. Aminobenzène‐Sulfonamides en Dioxyde‐1,1 de Benzothiadiazine‐1,2,4, en Présence D'Acide Formique

Published: September 2010

AbstractLe présent travail est consacré à l'hétérocyclisation en dioxyde‐1,1 de benzothiadiazine‐1,2,4 correspondant de six o.aminobenzène‐sulfonamides.II a été possible de généraliser la méthode spectroscopique de détection du formanilide intermédiate et de confirmer ainsi que le schéma réactionnel comprend deux réactions consécutives non compétitives. L'étude cinétique a conduit á la détermination des constantes de vitesse ainsi que des paramétres d'Eyring et de Hammett relatifs à chaque étape. Par ailleurs, on démontre que les constantes d'acidité des sulfonamides, déterminées au sein de l'acide sulfurique, sont régies par une relation log Ka/Kao ρκ Σσ (ρκ = 3,03; Kao = 1).Pour la première étape, le mécanisme proposé est celui d'une substitution a nucléophile variable (les différentes sulfonamides) sur support insaturé identique (l'ion formylonium). Tous les résultats expérimentaux peuvent être coordonnés et interprétés sur cette base: en particulier l'existence de deux constantes de réaction (ρI, ρ′I), l'une négative (constante réelle) et l'autre positive (constante apparente).L'hétérocyclisation elle‐même est une substitution intramoléculaire sur centre insaturé. Elle est peu sensible à l'action des substituants: en fait, la température expérimentale est voisine de la température isocinétique.
