Gel Permeation Chromatography of Alkali Cations in Methanol Effect Of Macromolecular Ligands on the Volume of Elution
Authors: Horrion Jacques , Sonveaux Etienne 
Published: September 2010

AbstractThe gel permeation of low concentrations of salts of alkali metals on Sephadex LH‐20 using methanol‐acetic acid as eluent allowed resolution of binary mixtures of the salts. The addition of poly(ethyleneglycol) monomethyl ether (M.W. 5000) (PEG) to the mobile phase induced a large reduction of the volume of elution of potassium and rubidium but sodium was little affected. A PEG‐18‐crown‐6 conjugate was synthesized and the association constants of the crown with various cations were determined. The PEG‐crown conjugate did not further accelerate the cations as compared to PEG alone.

Published: September 2010

AbstractThe reaction of bis(halodiphenylstannyl)methanes with HMPA leads to the formation of the one‐to‐one complexes (Ph2XSn)2CH2. HMPA (X‐Cl,Br,I). The reaction of bis‐1,3(chlorodiphenylstannyl)propane with HMPA yields the one‐to‐two complex (Ph2ClSnCH2)2CH2. 2 HMPA, whereas from bis(dibromophenylstannyl)methanes both the one‐to‐one and the one‐to‐two complexes (PhBr2Sn)2CH2‐n HMPA (n=1,2) have been isolated. The solid structure of (Ph2XSn)2CH2. HMPA (C=Cl,Br), determined by X‐ray diffraction, shows for both tin atoms a distorted trigonal bipyramidal structure, one by complexation of the HMPA, the other one by intramolecular coordination of a halogen atom. Temperature dependent 1H, 13C, 31P and 119Sn NMR and IR measurements prove the intramolecular mobility of these compounds.
Chimie Des Cyanates D'onium Copolymérisation Avec Le Toluène Diisocyanate Et Formation De Polyisocyanates ‐ Polyisocyanurates D'onium: Chemistry of Onium Cyanates Copolymerisation with Toi Yielding Onium Polyisocyanurates ‐ Polyisocyanates.

Published: September 2010

AbstractOwing to the lipophilic character of the tetraalkylonium cations many onium cyanates are soluble in aprotic organic solvents in which they show a high reactivity. In this paper we examine the reactions of onium cyanates (QNCO) with aromatic mono‐ and diisocyanates. Aromatic isocyanates react very rapidly with QNCO (co‐trimerization) at room temperature and yield quantitatively onium diarylisocyanurates (IV) (S: Ac, DME). In some solvents (e.g. DCM) co‐trimerization and trimerization to triarylisocyanurate (II) are observed (fig. 1). Onium polyisocyanurates polyisocyanates (scheme 1) are prepared from QNCO and diisocyanates (e.g. TDI), the first and rapid step being the co‐trimerization to compound (V). In the absence of QNCO, (V) undergoes slow trimerization to (VII) (fig. 2), but in the presence of QNCO co‐trimerization to onium polyisocyanurate (VIII) occurs. However, the ionic heterocyclization is not perfectly selective, but is accompanied by the trimerization to triarylisocyanurates. The polymers synthesized from the TDI‐QNCO systems are represented by formula (IX) or, in abbreviated form, (T)8 (R)n (NCO)a+2. Experimental values of parameters a, n, and the average number of adjacent heterocyclic anions, n, are presented in table 2. It is demonstrated that anionomers of high M.W. (a>10; n>100; n°5) and soluble in DCM can be prepared by this method. The important parameters in this polymerization are the nature of Q+ and that of the solvent (table 2).

AbstractIn the determination of platinum by atomic absorption spectrophotometry (AAS) ethanolamine was used to eliminate the interference effects of some organic compounds, by adding it to both sample and standard solutions. Also the mechanism of this elimination is discussed. These interference effects were examined with the continuous titration method to obtain stoichiometric ratios in the flame.

Published: September 2010

AbstractPhthalic imidine 1 is shown to be present in DMSO‐d6 solution as a 5:1 mixture of 3‐amino‐1H‐isoindol‐1‐imine (1a) and 1,3‐diiminoisoindoline (1i) by 13C chemical shift comparison with model compounds: 3‐(cis‐2,6‐dimethylmorpholino)‐1H‐isoindol‐1‐imine (3) and 2,3,4‐trihydroisoindolino[2,1‐a]pyrimidin‐6‐imine (4). The amino tautomer 1a also predominates in other solvents: CDC13, D2O, CD3OD.The N1,N3‐dimethyl derivative 2 also exists as a tautomeric mixture, in which 3‐methylamino‐1‐methylimino‐1H‐isoindole (2a) predominates over 1,3‐bis (methylimino)‐isoindoline (2i) as shown by 13C chemical shift comparison with 3‐dimethylamino‐1‐methylimino‐1H‐isoindole (5) and E‐6‐methylimino‐2,3,4‐trihydroisoindolino[2,1‐a]pyrimidine (6).1H and 13C NMR assignments are discussed in detail.

Phase‐Transfer Catalysis by Poly (Ethyleneglycol) 600 in the Biltz Synthesis of Phenytoin
Authors: Poupaert Jacques H. , Keyser Jean‐Luc De , Vandervorst Daniel , Dumont Pierre 
Published: September 2010

AbstractA reinvestigation of the Biltz synthesis of phenytoin was undertaken to selectively produce the hydantoin derivative instead of a mixture of the hydantoin and the glycoluryl derivative. A solution of this problem was found in carrying out the reaction in a two‐phase system (n‐butanol:water) and in the presence of a phase‐transfer catalyst (poly(ethyleneglycol)600). In these conditions, a 87–93 yield of phenytoin can be obtained. Extension of this approach to the synthesis of other hydantoin derivatives was also found superior to one‐phase conditions.

Authors: Huisgen Rolf , Fulka Claudia , Kalwinsch Ivars , Xingya Li , Mloston Grzegorz , Moran Joaquin Rodriguez , Pröbstl Albert 
Published: September 2010

AbstractThe cycloaddition of diazoalkanes to CS double bonds furnishes 1,3,4‐thiadiazolines which give rise to thiocarbonyl ylides and N2 in a cycloreversion. Thiocarbonyl ylides are nucleophilic 1,3‐dipoles which are interceptible by thiones or electron‐deficient alkenes and alkynes as dipolarophiles affording 1,3‐dithiolanes, dihydrothiophenes and thiolanes, respectively. In the absence of reaction partners, thiocarbonyl ylides undergo electrocyclization, dimerization, β‐H abstraction or Wagner‐Meerwein rearrangement.
Outstanding Problems of Hydrodesulfurisation Catalysis: Promoters, Product Distributions, and Activation Energies
Authors: Mitchell Philip C. H. , Scott Carlos E. 
Published: September 2010

AbstractActivities and product distributions in thiophene hydrodesulfurisation at 523–673K and 1 atm over Mo/A1203 catalysts promoted by Ru, Co, Ni and Co‐Nb/Al2O3 and Ni‐V/A12O3 catalysts are described. The promoters enhance the desulfurisation function and, except for uncalcined Ru, diminish the hydrogenation function of the catalysts. The Co‐Nb catalysts were inactive. The promotion of V catalysts by Ni shows that an MoS2‐type layer is not essential for synergy.Preliminary data on the Arrhenius parameters suggest compensation between the apparent activation energy, E, and the frequency factor, A, as the promoter mole fraction is changed.The results are consistent with a catalyst structure in which all or some promoters are dispersed by binding to unsaturated S atoms at the edge of MoS2 patches.
Temperature Programmed Reduction and Desorption Studies of CO‐Precipitated Cobalt‐Molybdenum Sulphide Powders
Authors: Hoodless R. C. , Moyes R. B. , Wells P. B. 
Published: September 2010

AbstractA series of unsupported cobalt molybdenum sulphide powders has been prepared by a variant of the homogeneous sulphide precipitation method. The series consisted of MoS2, eight powders with Co/(Co+Mo) ratios of 0.167 to 0.643, and CO9S8. The activity of these materials was tested using the hds of thiophen. The catalysts were characterised by deuterium adsorption at 673 K, TPR and TPD.A double maximum was found for the dependence of activity with Co/(Co+Mo) fraction, in a range similar to that found by other workers. Hydrogen retained by the catalyst, and deuterium adsorption at 673 K are not related to the hds activity. TPR and TPD measurements, however, show the same two‐peak behaviour as the activity across the composition range. The TPR behaviour shows two peaks of hydrogen uptake at 475 K and 650 K, the relative areas of which depend on the Co/(Co+Mo) ratio in a complex way. The high temperature peak is strongly correlated with hds activity, and this activity is related both to the formation of defect sites at high temperature and the availability of adsorbed hydrogen. The adsorbed hydrogen measured by desorption between 300 K and 872 K is greatest in the Co/(Co+Mo) range 0.167 to 0.445, the range of highest activity for conventional catalysts, whereas combination of the TPR and TPD results yields the same pattern as is obtained for hds activity.The results show that the behaviour with respect to hydrogen is strongly affected by the presence of both cobalt and molybdenum, the synergic effect is much greater than a combination of the components.
A Comparison of Some Catalytic Properties of Unsupported MOS2 and WS2 Catalysts Promoted by Group VIII Metals
Authors: Vrinat M. , Lacroix M. , Breysse M. , Frety R. 
Published: September 2010

AbstractUnsupported sulfided CoMo, NiMo, CoW and NiW catalysts prepared by comaceration (CM) method and homogeneous sulfide precipitation (HSP) method have been studied in hydrodesulfurization of dibenzothiophene and hydrogenation of biphenyl.Comparison of intrinsic rates shows that, for both reactions, the HSP catalysts are more efficient than the corresponding CM samples. Moreover, the promoting effect of Ni in hydrogenation is substantially higher than that of Co.From decomposition of the precursors, followed by differential thermal analysis, a parallelism appeared between all mixed catalysts prepared by the same procedure. For CM precursors, the decomposition features show the persistence of the character of Mo and W compounds and confirm the limited interaction existing between Co (or Ni) and Mo (or W) in the precursor state. On the contrary, for HSP precursors the exothermic peak is always recorded at a much lower temperature and a comparison with previous results obtained on CoMo (CM) and CoMo (HSP) catalysts suggests that a mixed phase probably exists in all the HSP samples.
Sulfided CO‐mo/AL2O3Catalysts: Carbon Monoxide Chemisorption and Surface Structures

Published: September 2010

AbstractThe interaction between Co and Mo ions has been examined on a series of Co‐Mo/Al2O3catalysts with constant Mo (6.3 % MoO3) and variable Co concentrations (0.5 ‐ 4.3 % CoO) by comparison with Co/Al2O3and Mo/Al2O3catalysts. The type of surface structures present in the systems in infered from the fraction of cobalt or molybdenum which can be dissolved in acidic or basic medium, and from carbon monoxide adsorption. The CO chemisorption is measured by pulses at 0°C and adsorbed species are studied by infrared spectroscopy. The interaction between Co and Mo ions in the sulfided state is shown by the appearance of a band at 2065 cm−1, partially irreversible in our conditions. It could correspond to highly reduced sites of the catalysts. This new type of site correlates with HDS activity. Results are consistent with the build up of a Co‐Mo‐S type phase. This phase is well dispersed and consists of small entities associating Mo and Co in the approximate ratio 3/2. Mo/Al2O3catalysts are found to be promoted essentially the same with Co or Ni atoms.
On The State of the Co‐MO‐S Model
Authors: Topsøie Henrik , Candia Roberto , Topsøe Nan‐Yu , Clausen Bjarne S. , Topsøe Haldor 
Published: September 2010

AbstractThe present article will discuss the recent developments which have taken place with the “Co‐Mo‐S model”. Some new results will also be presented to elucidate some of the controversies which have existed in the literature. The Co‐Mo‐S model, which was originally based on Mössbauer emission spectroscopy (MES) measurements, has now been confirmed and further developed by use of extended x‐ray absorption fine structure (EXAFS), infrared spectroscopy (ir), x‐ray photoelectron spectroscopy (XPS), high resolution and analytical electron microscopy (HREM and AEM), magnetic susceptibility and other methods. The following are some of the main conclusions: (i) Mo is present mainly as MoS2‐like phases; (ii) in the catalytically active Co‐Mo‐S structures, the promoter atoms are located at the edges of the MoS2‐like structures; (iii) the chemical and catalytic properties of the Co edge atoms are strongly influenced by the MoS2“support”; (iv) in typical alumina supported catalysts, the MoS3domains appear to be predominantly present as small single sheets which have a large fraction of the Mo atoms present at edge positions (this is an important property since it allows highly active catalysts to be prepared); (v) the presence of Co9S8, cobalt in the alumina or unpromoted MoS2is seen to have little influence on the HDS activity; (vi) in typical Co‐Mo/Al2o3catalysts strong interactions exist between Co‐Mo‐S and the support probably in the torn of Mo‐S or Mo‐O bridges to the alumina (this influences both the chemical and catalytic properties of Co‐Mo‐S); (vii) the Co‐Mo‐S model can explain the catalytic behavior of unsupported and supported catalysts including carbon supported catalysts; (viii) besides Co‐Mo‐S, evidence for similar Ni‐Mo‐S, Co‐M‐S, Ni‐W‐S and Fe‐Mo‐S structures has been found. The promotional effect depends on the nature of the atoms at the MoS2(or WS2) edges and for Fe‐Mo‐S, the effect is slightly negative; (ix) the nature of the active sites has been observed to be different in unpromoted and promoted catalysts; (x) for unpromoted Mo catalysts edge sites have a higher HDS activity than corner sites; (xi) Co‐Mo‐S and Ni‐Mo‐S type structures have also been observed to play a role in hydrogenation.

AlPO4‐Supported Rhodium Catalysts. VI.‐ Liquid‐Phase Hydrogenation of CH2‐CH‐r Compounds
Authors: Cabello J. A. , Campelo J. M. , García A. , Luna D. , Marinas J. M. 
Published: September 2010

AbstractThe hydrogenation of a wide variety of unsaturated compounds in the form CH2‐CH‐R was carried out under 0.55 MPa of hydrogen pressure and temperatures between 293–323 K, with methanol as the solvent, using 1 wt % rhodium‐on‐AlPO4catalysts. The catalysts are highly reactive towards the selective hydrogenation of the olefinic bond except for α‐ß‐unsaturated alcohols and aldehydes.The reaction rate is a function of both the substituents at the olefinic bond and the support of the rhodium catalysts. However, there is no linear relationship between electronic or steric effects on the reaction rate.Apparent activation energies, Ea, and Arrhenius constants, ln A, show a linear relationship, i.e. the compensation effect.

AbstractPyrethroid precursors (permethric and chrysanthemic acid esters) are efficiently synthesized by rhodium(II)‐catalysed cyclopropanation of the properly substituted conjugated diene. Reaction selectivities depend on both the catalyst counter‐ion and the diazoester alkoxy‐group (carbene precursor) and are attributed to non‐bonded interactions.

Abstract1,4,5,8‐Tetraazaphenanthrene‐N1‐oxide (II) reacts with POCl3to give equivalent amounts of 2‐chloro‐tetraazaphenanthrene (V) and 9‐chloro‐tetraazaphenanthrene (VI). Benzo [f] quinoxaline‐N1‐oxide (IV) gives with the same reagent 2‐chloro‐benzo [f] quinoxaline (IX, 57%) and 9‐chloro‐benzo[f]quinoxaline (X, 15%). This last result suggests that the chloride ion has entered position 9− of II rather than position 10−, in agreement with electronic effects.
