AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
The electrochemical activation of ethylene oxidation was studied over rhodium catalysts of different thickness (40, 100 and 160 nm) sputtered on top of a thin layer of TiO2 deposited on YSZ. The strong relationship between catalytic activity and oxidation ...

An organometallic 4d transition metal complex [CpRhCl2]2, together with commercially available dyes, was used to construct indicator displacement assays (IDAs) for the detection of peptides, amino acids, and nucleotides. The combination of the CpRh compl ...
Three-component Passerini reactions (P-3CR) of a wide range of aldehydes and isocyanides, with hydrazoic acid in toluene, in the presence of a [(salen)-AlMe]-complex catalyst afford 5-(1-hydroxyalkyl)tetrazoles in good-to-excellent yields and enantiomeric ...
Optically active 1,3-diethynylallenes (DEAs) were prepd. by enantioselective Pd-mediated SN2'-type cross-coupling and their abs. configuration was detd. by X-ray anal. Addn. of tetracyanoethene (TCNE) to donor-substituted DEAs affords novel 1,1,4,4-tetracy ...
Chiral rhodium(I) complexes activate allenyl tert-cyclobutanols efficiently through enantioselective insertion into a C-C σ bond of the cyclobutane. Ring expansion by this method produced cyclohexenones with quaternary stereogenic centers with excellent e ...
A [(salen)-AlIIICl] complex catalyzes the Passerini three-component reaction of an aldehyde, a carboxylic acid, and an isocyanide to afford alpha -acyloxyamides, e.g., I, with good to excellent enantioselectivity. A variety of nonchelating substrates can b ...
Structured supported ionic liquid-phase (SSILP) catalysis is a new concept with the advantages of ionic liquids (ILs) used as solvents for homogeneous catalyst and the further benefits of structured heterogeneous catalysts. This is achieved by confining th ...
Organophosphorus compounds found applications in varied fields of the organic chemistry: they are particularly present in natural compounds such as the deoxyribonucleic acid (DNA) and in the field of catalysis in which their utility is also proven. Thus, t ...
The water-sol. ruthenium(II) complexes [Cp'RuX(PTA)2]Y and [CpRuCl(PPh3)(mPTA)]OTf (Cp' = Cp, Cp*, X = Cl and Y = nil; or X = MeCN and Y = PF6; PTA = 1,3,5-triaza-7-phosphaadamantane; mPTA = 1-methyl-1,3,5-triaza-7-phosphaadamantane) were used as catalyst ...
