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.
A ruthenium meso-tetra[4-(vinylbenzoxy)benzyl]porphyrin catalyst with four meso-polymerizable side chains was synthesized in three steps from commercially available starting materials. The polymerizable side chains allowed the incorporation of this complex ...
Reactions of X2 (X = Br, I), P4 and Ag(CH2Cl2)[Al(OR)4] [R = C(CF3)3] in suitable ratios to prep. naked polyphosphorus cations were carried out and led to products which suggested these elusive cations as intermediates. At temps. >-30 Deg to rt the initial ...
A bimetallic complex, in which a RuCl2 (eta(2)C(2)H(4))(PCy3) fragment is connected via three chloro, bridges to a (eta(6)-p-cymene)RuCl2 fragment, has been synthesized and characterized by single-crystal X-ray crystallography. This complex was used to cat ...
A few years ago the concept of homogeneous arene hydrogenation catalysis was called into question, since many catalysts originally assigned as homogeneous have subsequently been shown to be precursors to heterogeneous ( colloidal or nanoparticulate) cataly ...
Arene hydrogenation by homogeneous catalysts is a highly controversial area of research, with many of the mononuclear complexes shown to catalyse the reaction, being found to be pre-catalysts to nanoparticles, on closer examination. The solvent properties ...
The prepn. of mesoporous Cr/AlPO was carried out under hydrothermal conditions. The catalyst was characterized by low angle XRD, N-adsorption, diffuse reflectance UV-visible spectroscopy, ESR and thermal anal. The catalytic activity was tested for vapor ph ...
Development of selective oxidation catalysts is a major concern of modern chemical industry. Among several systems, VTi-oxide based catalysts showed the most promising and versatile, able to catalyse key reactions like oxidation of o-xylene to phtalic anhy ...
This paper focuses on the mechanism by which a monoterpene undergoes a cyclocarbonylation reaction catalysed by a palladium complex. Evidence is provided, based on intermediate species observed under pressure or with various ligands, that the catalytic cyc ...
Electrochem. promotion (EP) of gas-phase catalysis with O2--conducting solid electrolytes is addressed. The behavior of the ref. electrode, prepd. by deposition of a gold film, was found to be quasi-reversible, 12O2/O2- being the potential detg. redox coup ...
The bimetallic ruthenium complex [(1,3,5-C6H3i-Pr3)Ru(m-Cl)3RuCl(C2H4)(PCy3)] has been synthesized by reaction of [(1,3,5-C6H3i-Pr3)RuCl2)]2 with one equivalent of PCy3 in the presence of ethylene. It can be used as a catalyst precursor for the controlled ...
