Le Mécanisme D'Extinction des Feux D'Hydrocarbures Par Les Halons
Authors: Antonik S. 
Published: September 2010

AbstractThe most recent theories on the inhibition of hydrocarbon flames by halogen containing compounds are critically reviewed: Mill's ionic theory, Creitz's theory and the theory of inhibition by HBr. New results from simultaneous experiments on halons‐H2‐air and halons‐air mixtures have given a new insight into the mechanism of extinction of hydrocarbon fires by these compounds. More precisely, the new mechanism takes into account some valuables processes which are present separately in the three mentioned hypothesis.

Published: September 2010

AbstractA new method is described to analyse the binary mixture of folpet and fenamiphos, using the first derivative spectrophotometry obtained by mathematical treatment of the data. Calibration graphs were linear between 1.0 to 15.0 μg·mL−1 of folpet and between 1.2 to 27.9 μg·mL−1 of fenamiphos. The method has been applied for determining both pesticides in commercial formulations and groundwater at ng.mL−1 levels after a preconcentration step with C18.

Proton NMR Relaxation Studies in Aqueous Solutions of Sugars with Alkali Halides
Authors: Sattiacoumar S. , Arulmozhi V. 
Published: September 2010

AbstractProton Magnetic Resonance (PMR) relaxation time measurements were performed in aqueous solutions of maltose and galactose as a function of sugar and alkali halide concentration. The experimental data unambiguously show that the presence of alkali halides highly influences the PMR relaxation process. The nature of molecular interaction in this ternary system is explained on the basis of two state fast exchange model and structure ordering/disordering of alkali halides.

Authors: Rouchaud J. , Gustin F. , Moulard C. 
Published: September 2010

AbstractMethyl 2‐ethylbutyrate (3) plus lithiumdiisopropylamide reacted with methyl iodide to give methyl 2‐ethyl‐2‐methylbutyrate (4). The methylene carbanion of acetonitrile‐generated with lithiumdiisopropylamide‐ reacted with 4 to give 4‐ethyl‐4‐methyl‐3‐oxohexanenitrile (5). 3‐Ketonitrile 5 reacted with hydroxylamine after 20 min of heating to reflux in ethanol to give 4‐ethyl‐4‐methyl‐3‐oxohexanitrile oxime (6). This in aqueous dilute HC1 was selectively and quantitatively transformed into 5‐amino‐3‐(l‐ethyl‐l‐methylpropyl)‐isoxazol (I). Longer heating of 5 with hydroxylamine directly generated a mixture of 7 with its isomer 3‐amino‐5‐(l‐ethyl‐l‐methylpropyl)isoxazol (7b). Reaction conditions were studied for optimization of the 5‐aminoisoxazol 7 synthesis.
Unexpected Hydrolysis of 5‐Aminoisoxazolbenzoylamide Herbicide Isoxaben into 5‐Isoxazolinone
Authors: Rouchaud J. , Gustin F. , Moulard C. , Plisnier M. 
Published: September 2010

AbstractThe benzoylamide derivative of 5‐aminoisoxazol, i.e. the herbicide isoxaben 1 (N‐[3‐(1‐ethyl‐1‐methylpropyl)isoxazol‐5‐yl]‐2,6‐dimethoxybenzamide) was transformed by aqueous acid hydrolysis into the unexpected 5‐isoxazolinone 3 (3‐(1‐ethyl‐1‐methylpropyl)isoxazolin‐5–one) plus mainly 2,6‐dimethoxybenzamide 4. The expected 5‐aminoisoxazol 7 (5‐amino‐3‐(1‐ethyl‐1‐methylpropyl)isoxazol) was not generated, except in very low amounts when high acid concentrations were used. In separate hydrolysis trials made in similar aqueous acid conditions, it was observed that the 5‐aminoisoxazol 7 and 5‐isoxazolinone 3 were not transformed. The 5‐isoxazolinone 3 formed by isoxaben 1 acid hydrolysis thus was the first generated product, and was not formed by the consecutive nucleophilic substitution of 5‐aminoisoxazol 7 which would have been formed in a first step. This unexpected 5‐amino C‐N bond cleavage by nucleophilic attack of H2O at the 5‐C of the isoxazol ring of isoxaben 1 ‐instead of the usual amide CO‐N bond cleavage‐ probably is due to the positive charge existing at the 5‐C atom of the isoxazol ring. The acid hydrolysis pathway observed for isoxaben 1 also is the main soil metabolism pathway. The absence of formation of an aromatic amino compound by chemical hydrolysis reduces the concern as to their potential tranformation into carcinogenic nitroso or azo compounds in soil. On the other hand, isoxaben 1 was not hydrolyzed in aqueous dilute alkali.

A Convenient Method for Heterolytic Chlorination with Sulfuryl Chloride and Catalysts for the Generation and Recycling of Chlorine
Authors: De Buyck Laurent , Accou Peter 
Published: September 2010

AbstractBy catalyzed decomposition of hot sulfuryl chloride chlorine is produced in the presence of substrates of relatively low reactivity. A condensor system equipped with a cooled solid catalyst recovers and recycles chlorine otherwise escaping with the waste gas. This principle was successfully applied for the heterolytic selective α,β,β‐trichlorination of ethers in the dark. For the equilibrium production of chlorine in hot sulfuryl chloride salts of organic bases were active catalysts at very low concentration, while some cyclic ethers showed autocatalytic activity. Pellets of activated carbon or anion exchanger resin were suitable for a cold catalysis. The recycling improved from about 86% at room temperature to almost quantitative below −10°C over reaction periods up to 6 days.

Mutal interactions between hydrogen bonds in alcohols ‐ nuclear magnetic relaxation study
Authors: Srinivasa Rao A. , Arulmozhi V. , Rajalakshmi S. 
Published: September 2010

AbstractProton NMR relaxation times T1 and T2 were measured in methonal, ethanol, propanol and butanol at a temperature of 37°C and at an RF frequency of 20 MHz. The hydrogen bond energies of the above alcohols are in the range 2.33‐4.56 Kcal/mole. The relaxation time T1 is found to decrease with increase of hydrogen bond energy in these alcohols and this is explained by postulating mutal interactions between adjacent hydrogen bonds.

Published: September 2010

AbstractQuantum chemical (CNDO‐CI‐1) simulation and theoretical analysis of UV absorption spectra of 2‐amino‐, 2‐methylamino‐, 2‐anilino‐, 2‐acetamido‐, and 2‐benzamido‐pyridines were carried out. A comparison of results with experiment provided information on tautomerism and rotamerism in abovementioned compounds in solution. Contrary to some literature data 2‐aminopyridine in solution exists in dimeric form of 2‐pyridylamine. Also 2‐methylaminopyridine in solution forms a similar dimer. 2‐Anilinopyridine appears in solution as cis‐1 H‐pyridine‐2‐phenylimine tautomer. Both acylamino derivatives of 2‐aminopyridine tautomerize with involvement solely of the carbonyl group to form hydroxyethylideno‐ and hydroxybenzylideno‐2‐aminopyridines, respectively.

Concerted and Stepwise Mechanisms in Metal‐Free and Metal‐Assisted [4+3] Cycloadditions Involving Allyl Cations
Authors: Fernández Israel , Cossío Fernando P. , de Cózar Abel , Lledós Agustí , Mascareñas José Luis 
Published: September 2010

AbstractThe thermal [4+3] cycloaddition reaction between allenes and tethered dienes (1,3‐butadiene and furan) assisted by transition metals (AuI, AuIII, PdII, and PtII) was studied computationally within the density functional theory framework and compared to the analogous non‐organometallic process in terms of activation barriers, synchronicity and aromaticity of the corresponding transition states. It was found that the metal‐mediated cycloaddition reaction is concerted and takes place via transition structures that can be even more synchronous and more aromatic than their non‐organometallic analogues. However, the processes exhibit slightly to moderately higher activation barriers than the parent cycloaddition involving the hydroxyallylic cation. The bond polarization induced by the metal moiety is clearly related to the interaction of the transition metal with the allylic π* molecular orbital, which constitutes the LUMO of the initial reactant. Finally, replacement of the 1,3‐butadiene by furan caused the transformation to occur stepwise in both the non‐organometallic and metal‐assisted processes.
