A clear description of the paths of thermal decomposition of complex borohydrides represents a crucial step forward to their utilisation as a reservoir of hydrogen and hence as materials for solid state hydrogen storage. We present in this work a theoretic ...
This study aims at an investigation of the impurity gases emitted during the decomposition of borohydrides. For this we have set up a quantitative gas analysis based on a combination of FTIR spectroscopy and gravimetry. We show that the emission of various ...
Gold nanoparticles (NPs) stabilized by carboxylate modified polyvinylpyrrolidone have been prepared and fully characterized. The gold NPs efficiently catalyze the aerobic oxidation of benzyl alcohol in water at ambient temperature and are easily separated ...
The reaction of (-)-(1E,3Z)-2-methyl-1-((1S)-1-phenylethoxy)penta-1,3-dien-3-ol benzoate with allyltrimethylsilane in SO,- and in the presence of a catalytic amount of Tf2NTMS gives a silyl sulfinate intermediate that furnishes (-)-(6Z,1'S,4S,5S)-5-methyl- ...
The knowledge and understanding of the mechanism as well as the rate constant of the solvent exchange reactions are fundamental, since these reactions represent an important step in complex formation reactions on metal ions. Solvent exchange reactions in a ...
NiII complexes of the new pincer amidobis(amine) ligand are described. The Ni chloride complex catalyzes Kumada-Corriu-Tamao coupling of unactivated alkyl halides with alkyl Grignard reagents, as well as double C-C coupling of CH2Cl2 with alkyl Grignard re ...
Thermodynamic solubility calculations are normally only related to thermodynamic equilibria in solution. In this paper, we extend the use of such solubility calculations to help elucidate possible precipitation reaction pathways during the entire reaction. ...
Chemoselective autoxidation of 4-imino-1,5-dimethyl-3-(4-nitrophenyl) imidazolidin-2-one (1b) to its 5-hydroxy derivative 2 occurred in solutions of DMSO-d(6), acetonitrile-d(3) or refluxing ethanol. Also bis(imidazolidin-5-yl) peroxide 5 was isolated as a ...
The Diels-Alder reaction has been examd. in room temp. ionic liqs. with high molar concns. of Lewis acids under various conditions. A molar ratio of 10% catalyst gave a large increase in the selectivity and the yield of the reaction. The effect of catalyst ...
The syntheses and single crystal X-ray structural analysis of five novel hetero- and homometallic μ3-oxo trinuclear cluster with the formula [FeIII2MII(μ3-O)(μ-O2CCH3)6(4-Rpy)3] · x(4-Rpy) · y(CH3CN) where R ) Ph for 1(Fe2Mn),2(Fe2Fe), 3(Fe2Co), 4(Fe2Ni) a ...
