Mössbauer study of the substituent effect in iron (III)‐complexes of nuclear substituted benzohydroxamic acids
Authors: Kane S. N. , Sharma A. K. , Gupta Ajay , Khadikar P. V. , Ali S. M. 
Published: September 2010

AbstractA series of Tris‐(hydroxamate)‐tri‐aqua complexes of iron (III) with benzohydroxamic and nuclear substituted benzohydroxamic acid derivatives as ligands were investigated by Mössbauer spectroscopy. The substitutions changed the electron density on the donor atoms of the legend moiety by their electrophelic and / or nucleophelic nature and changed the symmetry of the complexes by their differential space requirements. Both the effects are reflected in the isomer shifts as well as the quadrupole splitting values.
Reactions of 3,5‐Diamino‐4‐Arylazopyrazoles with chlorinated quinones
Authors: Hassan Alaa A. , Mohamed Nasr K. , Aly Ashraf A. , Mourad Aboul‐Fetouh E. 
Published: September 2010

Abstract3,5‐Diamino‐4‐arylazopyrazoles 1a‐d reacted with 3,4,5,6‐tetrachloro‐1,2‐benzoquinone(CHL‐o) via charge‐transfer (CT) complex formation giving bisimidazobenzobispyrazoles 5a‐d. On mixing either 2,3,5,6‐tetrachloro‐1,4‐benzoquinone(CHL‐p) or 2,3‐dichloro‐1,4‐naphthoquinone(DCHNQ) with 1a‐d in DMF, pyrazoloquinazolinetrione 8a‐d and 9a‐d derivatives were formed.
Correlation of X‐Ray K‐Absorption parameters with wiener indices
Authors: Kekre Pravin A. , Joshi K. P. , Khatri Sunil , Mishra Ashutosh 
Published: September 2010

AbstractA new application of Wiener indices in estimating some X‐ray absorption parameters is described. X‐ray K‐absorption parameters are correlated with Wiener indices. Some hydroxy substituted pyridine copper(II) and cobalt(II) complexes are used to establish this type of correlation.
Perestroika effect. A novel example of electroviscosity
Authors: Mazurkiewicz Jozef , Tomasik Piotr 
Published: September 2010

AbstractA novel type of rotary viscometer was constructed for rheological studies in an high intensity electric field. The title effect was observed for 1,4‐dioxane containing small but defined amounts of certain compounds. The application of the electric field caused destruction of the molecular arrangement in the solution. It was manifested by a sudden, temporary decrease of viscosity. The original molecular order in the solution was then soon reconstructed, nevertheless the factor causing the disorder was not removed. The removal of the potential gradient evoked similar disorder in the solutions under study. This disorder turned again into original pattern as shown by restored viscosity. The magnitude of this “electric shock” roughly depended on dielectric constant and concentration of the compound added to 1,4‐dioxane.
X‐ray structure of trans‐(2,5)‐bis(methoxymethyl)pyrrolidino carbohydroxamic acid
Authors: Tinant B. , Declercq J. P. , Gouverneur V. 
Published: September 2010

AbstractThe structure of the title compound has been established by X‐ray diffraction analysis. C9H18N2O4, Mr=218.25, monoclinic, P21/c a=9.249(6), b=10.138(2), c=12.175(6)Å, β=92.21(5)°, V=1141(1)Å3, Z=4, Dx=1.27g· cm−3, CuKα radiation (λ=1.54178Å). The final R index is 0.056 for 1860 observed reflections. The data confirm the trans relationship between the two methoxymethyl groups. Large deformation from the synperiplanar conformation and a very long C‐N bond are observed in the hydroxamic group. An intramolecular hydrogen bond occurs between the NH and an ether oxygen. Molecules form dimers by doing intermolecular H‐bonds between the carbonyl and the hydroxyl of the hydroxamic acid.
Réaction du Méthylazide Avec des Oléfines Cinnamiques, Crotoniques et Acryliques. Étude des Composés Obtenus
Authors: Le Hetet G. , Carrié R. , Benhaoua H. 
Published: September 2010

AbstractMethylazide reacts with the title olefines and gives expected 1,2,3‐triazolines in equilibrium with corresponding amino diazo compounds. Because this equilibrium, E and Z olefines gives the same result, and the addition do not seem stereospecific. Thermolysis of this mixture gives one or two enamines. Oxidation with KMnO4 leads to triazoles. Reaction between methylazide and methyl acrylate or methyl vinylketone are more complicated because the amino diazo compounds react with starting alkene.
Immobilization and characteristics of β‐galactosidase on polymer resin
Authors: Xuyuan Li , Kehao Zhao , Yanfa Men , Weixia Tu 
Published: September 2010

AbstractSephadex G‐100 modified with chloracetic acid and CEAH was prepared into cationic and anionic carriers and actived by CNBr. β‐galactosidase β‐D‐galactoside galacto hydrolase EC3. 2. 1. 23) isolated and partially purified from gram chicken bean was immobilized on modified Sephadex G‐100 by means of adsorption of ions and crosslinked reaction. Both the anionic and cationic gel carriers have high protein binding capacity and high yield of enzyme activity. Kinetic results showed that the enzyme activity attained its maximum at 57°C for cationic carriers and 52°C for anionic carriers. In addition, the operational pH range of the immobilized preparations were increased. The immobilized enzymes showed good storage stability at room temperature than that of soluble enzyme. Results of repeated batch experiment suggested that the immobilized enzymes could be reused.
Diazoaldehyde Chemistry, Part 2: Transdiazotization of β,γ‐ and β,δ‐Dioxoaldehydes
Authors: Sezer Özkan , Hanci Nalan , Anaç Olcay 
Published: September 2010

AbstractBase induced ring opening reactions of 2‐(substituted)‐4H‐pyran‐4‐ones (R=H, Ph) gave the corresponding 5‐(substituted)‐3,5‐dioxopentanals, which were in turn transdiazotized with 2‐azido‐1‐ethylpyridin‐1‐ium BF4. The reactions gave 5‐(substituted)‐2,4‐bis(diazo)‐3,5‐dioxopentanals and 4‐(substituted)‐1,3‐bis(diazo)‐2,4‐butandiones, the latter being the deformylating diazo transfer products. A two‐fold deformylation product (1,3‐bisdiazo‐2‐propanone) was observed in the reaction of 3‐oxopentandial, which was also synthesized from tosyl azide and 1,5‐bis(N‐methyl‐N‐phenylamino)‐trans,trans‐1,4‐pentadiene‐3‐one in low yield. 4‐(substituted)‐3‐diazo‐2,4‐butandieones also formed as side products. The reactions of 4,4‐dimethoxy‐3‐oxobutanal and ethyl 2,4‐dioxobutanoate with the same azidinium salt gave 1‐diazo‐3,3‐dimethoxy‐2‐propanone and ethyl 3‐diazo‐2‐oxopropanoate respectively.
Successive‐substitution methods in chemical‐equilibrium calculations: An application to aqueous simple ampholytic electrolytes
Authors: Cardinali Mario E. , Giomini Claudio , Marrosu Giancarlo 
Published: September 2010

AbstractFor each of the aqueous electrolytes, whose acid‐base behaviour is described by only one acidic, and only one basic, ionization equilibrium, the electroneutrality equation is rearranged (as described in Appendix) to such a form that the successive‐substitution algorithm to which it can give origin always converges to the root of the corresponding equation, i. e., to the hydrogen‐ion concentration of the solution it refers to. The converging properties of these algorithms are given a qualitative explanation.
Equilibrium deposition filtration: A simple technique to prepare very active and selective catalysts
Authors: Papadopoulou Ch. , Karakonstantis L. , Matralis H. K. , Kordulis C H. , Lycourghiotis A. 
Published: September 2010

AbstractResults concerning the catalytic activity of catalysts prepared by Equilibrium Deposition Filtration (EDF) and corresponding catalysts prepared by conventional impregnation techniques are reported. These results show that the EDF and co‐EDF methodologies may be used for preparing very active catalysts even with quite high loading.
Reactions of acyl isothiocyanates with diphenyldiazomethane
Authors: L'Abbé Gerrit , Francis Agna , Dehaen Wim , Bosman Joris 
Published: September 2010

AbstractThe title reactions yield labile 4,5‐dihydro‐1,3‐oxazole‐4‐spiro‐2′‐thiiranes 4 which isomerize in solution to the thietan‐3‐imines 5. This isomerization also occurs when the spiro compounds are heated to their melting points, but here the desulfurized products 8 and 9 are also formed in some cases. These are also the products obtained by SO2 extrusion of the sulfones 10 derived from 5.

Authors: Cado Françoise , Bazureau Jean Pierre , Hamelin Jack 
Published: September 2010

Abstract2‐Substituted (1H)‐perimidine 1 reacts with various 2‐chloroacyl chlorides 3 to afford new ethyl 2‐oxo‐Δ2. pyrrolino‐[1,2‐a]‐(4H)‐perimidine‐3‐carboxylates 5 in good yields by a N,C‐cyclocondensation reaction sequence. The 1H, 13C NMR spectrum of some representative compounds are discussed. The reactions of 1 with trans‐cinnamoyl chloride 6 and with 3‐chloropropanoyl chloride 8 as β‐dielectrophiles have been investigated and gave directly the corresponding fused perimidines 7 with reverse regiochemistry.
