Produits Lourds Insaturés de la Radiolyse du Diméthyl‐2,3 Butane en Phase Solide III. Processus Ioniques
Authors: Tilquin B. , Bombaert‐Michielsen C. 
Published: September 2010

AbstractThe γ‐radiolysis of solid solutions of N2O, Ar, and CCl4 in 2,3 dimethylbutane has been examined at 77 K. With N2O and Ar, no significant changes in yields of the unsaturated heavy products are produced, however, the yield of the major products (deshydrodimer) was increased. With CCl4, yields of the heavy products were all reduced.In the case of N2O on Ar as solutes, the results show that ionic mechanism does not produce unsaturated heavy products, by contrast the radical cation does produce at least one of the deshydrodimers.
Study of the mesomorphic behaviour of ternary mixtures of alkoxybenzalazines by means of the Scheffé design
Authors: Marcos M. , Meléndez E. , Serrano J. L. , Mathieu D. , Phan Tan Luu R. , Elguero J. 
Published: September 2010

AbstractThe Scheffé design was applied to a ternary mixture of 4,4′‐diethoxy‐2,2′‐dihydroxy‐α,α‐dimethylbenzalazine, 4,4′‐dipropoxy‐2,2′‐dihydroxy‐α,α'‐dimethylbenzalazine and 4,4′‐dibutoxy‐2,2′‐dihydroxy‐α,α‐dimethylbenzalazine in order to improve the physical properties of each individual component. Twenty‐two different mixtures were selected and their thermodynamical properties measured. A third order model was chosen to account for the experimental measurements. Thus, it was possible to determine the best region in the ternary diagram.

(III) dl 2,3‐bis(phenylthio)dimethylsuccinate, C18H18S2O4, is orthorhombic, Pbnb with α=15.265(3), b=16.618(4), c=7.063(2)Å, V=1791.7(6)Å3, Z1 (III) dl 2,3‐diphenoxy dimethylsuccinate, C18H18O6 is orthorhombic, Pcab with α=21.612(6), b=17.662(4), c=9.029(2)Å, V=3446.5(6)Å3, Z=8. (V) dl 2,3‐diacetoxy dimethylsuccinate, C18H14O8, is orthorhombic, Pca21, with α=10.879(2), b=13.558(2), α=9.133(2)Å, V=1347.1(5)Å3, Z=4.The geometry of the five molecules is quite normal. These results are compared with those concerning dimers with quaternary central carbon atoms (R1R2R3C)2 in which a long central C‐C bond was found.

AbstractC13H10N4OHg2Cl2 is orthorhombic, Pnab with Z=4, a=7.775(1), b=10.375 (1), c=20.117(3)Å, V=1622.8(3)Å3, Dm=2.95, Dc=2.91 Mg m−3, F(000)=1272, μ(CuKα)=39.12 mm−1, Mr=710.34, R=0.114 for 1173 independent reflections.π‐Electron delocalisation in the Ph‐N‐N‐C‐N‐N‐Ph chain, as was found in the structurally related dithizone molecule, does not occur but a localised single bond for C(Ph)‐N and a localised double bond for N‐N show up. Each mercury atom, sandwiched between the planes of two benzene rings, forms an almost linear bond with a nitrogen and a chlorine atom in a digonal characteristic coordination.
Trigallic Acid or Trimeric Gallic Acid
Authors: Delahaye P. , De Bruyn A. , van Damme F. , Verzele M. 
Published: September 2010

AbstractTrigallic acid was isolated by Counter Current Distribution from a partial acid hydrolysate of Chinese tannic acid. Trigallic acid in polar solvents solution occurs in four isomeric forms. This is revealed by the four peaks obtained with reversed phase high performance liquid chromatography. Their ratio is function of the solvent. The four isomeric trigallic acid forms are in equilibrium. They result from the meta‐meta, meta‐para, para‐meta and para‐para coupling of the three gallic acid building blocks in trigallic acid. This was proved by spectroscopic and chemical methods.

Authors: Mahmoud M. R. , Hamed M. M. A. , Youssef M. S. K. , El‐Gyar S. A. 
Published: September 2010

AbstractSchiff bases, arylidenes‐anthranilic acid complexes with Th(IV), UO2(II), La(III), Ce(III) and Zr(IV) have been isolated. The structure of the complexes is recognized by elemental analysis, electronic spectra and i.r. spectral data as well as conductance measurements. The salicylidene‐anthranilic acid L3 is coordinated to the metal ion as bivalent tridentate ONO ligand (L−2) while the other compounds studied are coordinated to the metal ion as monovalent bidentate ON ligand. The molecular structure effect of these compounds on the strength of their complexes is discussed.It is identified that the Cu(II) complex of L3 can act as bidentate ligand, coordinating through its cis oxygen atoms to form binuclear metal complexes.

Published: September 2010

AbstractThe NAD+ analogue 3‐acetylpyridine adenine dinucleotide (3‐AcPyAD+) has been studied in the co‐enzyme recycling system ethanol‐ketone‐3‐AcPyAD+‐HLAD. All reaction parameters are tested in analogous conditions as for the NAD+‐recycling system. The stereospecificity of the new system is investigated for the reduction of 4‐, 3‐ and 2‐alkylcyclohexanones. The new recycling system is kinetically and stereochemically very similar to the NAD+ system, but 3.2 times slower.
A Perturbational Force Field Calculation Explains the Increased Conformational Inversion Barrier of 1α,4α‐Dihydroxy‐cis‐1,2,3,4,4a,5,8,8a‐Octahydronaphthalene
Authors: Vanhee P. , Tavernier D. 
Published: September 2010

AbstractThe Gibbs activation energy for the inversion of the (half‐chair) chair conformers of the title compound has been obtained from dynamic 13C‐NMR: ΔG≠239=44.7 kJ mol−1 (k=0.5). It is thus 3.4 kJ mol−1 higher than for the parent hydrocarbon. This increase is rationalized by a perturbational force field study. The reliability of the perturbational calculation was tested by a comparison of calculated and experimental conformational equilibria in various 1‐ and 2‐oxygenated cis‐decalins.

AbstractThe new complexes Pt(NopyH)2Cl2, Pt(NmpyH)2Cl2, Pt(BpnH2)Cl2·1.5H2O, Pt(Bpn).4H2O and Pd(Bpn).H2O, where NopyHN‐(2‐aminophenyl)pyridine‐2′‐carboxamide, NmpyHN‐(3‐aminophenyl)pyridine‐2′‐carboxamide and BpnH2=N,N′‐bis(2′‐pyridinecarboxamide)‐1,8‐naphthalene, have been prepared. Properties, molar conductance measurements and spectral (d‐d, IR and 1H‐NMR) data are discussed in terms of possible structural types and the nature of the bonding. The deprotonated complexes have N4 square planar coordination, while in the compound Pt(BpnH2)Cl2·1.5H2O the ligand displays an apparent unique trans‐bidentate function. NopyH and NmpyH act as monodentate ligands, bonding through the amino group.
Electron Donor‐Acceptor Complexes of Iodine with Imidazole and Some of its Derivatives
Authors: Mahmoud Refat A. , El‐Samahy Ahmed A. , Rabia Mostafa M. 
Published: September 2010

AbstractElectron donor‐acceptor complexes of iodine with imidazole and some of its derivatives have been studied spectrophotometrically in chloroform. Equilibrium constants and molar extinction coefficients of the charge‐transfer complexes as well as the thermodynamic properties were computed at different temperatures. From the results obtained it has been concluded that the charge‐transfer complexes formed are of the “n” type and the imidazole molecule presents a single energetically favorable donating site for charge transfer complex interaction (i.e. the unshared pair of electrons on the pyridine‐nitrogen N‐3). Furthermore, the effect of the molecular structure of the investigated compounds have been studied. It is found that the equilibrium constants increase regularly as the electron donating character of the substituent is increased. On the other hand, the equilibrium constants decrease with increasing electron withdrawing character of substituents. This is due to the fact that the electron donating group increases the basicity of the donor molecule while the withdrawing group decreases the basicity of N‐3 in the donor molecule.
Vibrational Spectra of 1,4,5,6‐Tetrahydropyrimidine‐2‐Thione and ‐2‐One

Published: September 2010

AbstractThe infrared and Raman spectra of 1,4,5,6‐tetrahydropyrimidine‐2‐thione (Tpt) and‐2‐one (Tpe) have been measured; polarized infrared spectra of Tpt have also been obtained. An assignment of most of the observed bands has been proposed on the basis of polarized infrared spectra, Raman spectra and analogy with the spectra of related compounds. The polarized infrared spectra of imidazolidine‐2‐thione have also been measured as a model compound for comparison with Tpt.

AbstractThe X‐ray molecular structure of the ß‐trilaurin has been refined starting from the X‐ray model of ß‐tri‐ll‐bromoundecanoin (1). The interatomic distances and angles have been defined with a precision of 0.01 Å and 0.1° respectively. They are compared with those of the ß‐tricaprin (2). In both compounds, we observe a chair‐conformation for the molecule with all the hydrocarbon chains which lie in parallel plans.

Authors: Antelo J. M. , Arce F. , Casado J. , Castro R. , Sanchez M. E. , Varela A. 
Published: September 2010

AbstractStudying the kinetic behaviour of the system 2‐ethylaminoethanol+hypochlorite under various experimental conditions shows that the rapid formation of N‐chloro‐2‐ethylaminoethanol (t1/2 <1 min) is followed by its slower decomposition, the exact rate of decomposition depending on the pH of the medium. N‐chloro‐2‐ethylaminoethanol is most stable in the range pH 4.5–7.0, where its half‐life is approximately 12.0 days at 25°C.

Authors: Compagnon Paul‐Louis , Kimny Tan , Compagnon Odette 
Published: September 2010

AbstractThe adicity of methyl bonded to pyridine nucleus of the s‐collidine depends on the solvent and the counterion nature. With Li+ or Na+ cations in Et2O, we have observed the decreasing acidity order: NH3 > Me‐2 > o‐tolunitrile > Me‐4; with Li+ or Na+ in liquid NH3: o‐tolunitrile > Me‐4 > NH3 > Me‐2. On the other hand, with K+ in Et2O or in liquid NH3: Me‐4 Me‐2 > NH3. An estimate for the pKa value of the s‐collidine (4‐methyl group) is ∼︁∼29 at –33°C in liquid NH3, with Na+ as counterion.

Authors: Wolny R. , Koll A. , Sobczyk L. 
Published: September 2010

AbstractThe dipole moments of 30 complexes of oxygen bases with various 2, 6‐dichlorophenols have been measured. The range of ΔpKa = (pKa (BH+) ‐ pKa(AH)) of the complexes varies from ‐9 to +2. The calculated values of the hydrogen bond polarity Δμ have been correlated with ΔpKa based on the Huyskens and Zeegers‐Huyskens proton transfer equilibrium model. Considerably high values of ΔμHB (with no proton transfer), and a small ΔpKa value of the inversion point, at which an equal population of non‐proton‐transfer and proton‐transfer states takes place, are characteristic for the systems studied.

Published: September 2010

AbstractA study of the DC polarographic behaviour of the lanthanide ion dysprosium(III) in an aqueous solution of 0.1 M N(CH3) 4ClO4 has been made. At the very negative potentials where the reduction of Dy(III) takes place, there are several difficulties in the polarographic experiments. Multiple waves are observed, which are associated with the presence of different hydroxycomplexes at the electrode surface.

Authors: Vassileva‐Dimova M. P. , Ivanov I. P. , Noninski Ch. I. 
Published: September 2010

AbstractA coneshaped self‐cleaning rotating electrode (1,2) was used for the investigation of the electrochemical oxidation of methanol in a 0.5 M CH3OH+0.5 M H2SO4 upon an unchanged and continuously renewed surface of a platinum electrode. It was shown that the increase of the speed of renewal of the electrode surface within the potential range 0.50 − 1.60 V leads to a significant increase of the rate of methanol oxidation. It was found that the shape of the i‐y curves obtained during the oxidation of methanol upon a continuously renewed surface differs from the shape of the same curves upon unchanged electrode surface. The observed current maximums at 0.05, 0.85 and 1.35 V upon unrenewed surface have tendency towards disappearing at high rotation speed. A tendency towards disappearing of current maximums is also observed in solutions of methanol when some halide ions are present.

Cyclopolymerization and Conformation of Dimethacrylamides in Polymer Matrices
Authors: Jakus Catherine , Smets Georges , Zeegers‐Huyskens Thérèse 
Published: September 2010

AbstractN‐phenyl (PDMA) and N‐methyl (MDMA) dimethacrylamide and unsubstituted dimethacrylamide (DMA) have been polymerized in polyvinylchloride film, and the resulting polymers and oligomers were analyzed by infrared and 1H‐NMR spectrometry. The structure of poly (PDMA) and poly (MDMA) corresponds to five‐membered recurring units without unsaturated side groups. On the contrary poly (DMA) contains both five‐ and six‐membered rings as well as some unsaturation. The structures are however identical to those of the corresponding polymers prepared in benzene solution. Consequently the reaction medium does not affect the cyclopolymerization of these dimethacrylamides. A further infrared analysis of the monomers in solution and in the solid state (KBr pellets and PVC films) suggests that the monomers preexist already in a conformation suitable for cyclopolymerization.

Radicals and Radical Ions Derived from 1,3‐Dienes
Authors: Courtneidge John L. , Davies Alwyn G. 
Published: September 2010

AbstractRecent improvements in experimental methods have made it possible to generate radicals and radical ions derived from simple 1,3‐dienes, so that their e.s.r. spectra can be observed in fluid solution.Photolysis of various cyclopentadienylmetallic compounds, or even of pentamethylcyclopentadiene itself, serves as a source of the corresponding cyclopentadienyl radicals, and the former method can be extended to the preparation of the fulvalene and pentalene radical anions.Cyclobutadiene radical cations are formed when the complexes formed between dimerised dialkylalkynes and aluminium chloride are photolysed. Di‐t‐butyl‐ethyne may also undergo a double nucleophilic rearrangement when it is treated with aluminium chloride, resulting in the formation of the hexamethylbutadiene radical cation, which can also be prepared from hexamethylbutadiene itself.Radical anions and cations can be regarded as being the conjugate bases and acids, respectively, of neutral radicals, and this principle has been exploited in the generation of cyclopentadiene radical cations from the photolysis of cyclopentadienes in acid solution.
