Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
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.
New methods that allow the generation of transition metal-based catalysts and receptors are discussed. It is shown that heterobimetallic, halogeno-bridged complexes are well-suited for screening assays in combinatorial catalysis. Metal catalysts with a str ...
This review seeks to evaluate the role of low oxidation state transition metal clusters (metal carbonyl clusters) in catalysis. The review commences with a discussion of the cluster surface analogy and then proceeds to discuss whether catalysis takes place ...
Reactions of tBuP(NH2)2 with Group 13 trialkyls MR3 (M = Al, Ga, In; R = Me, tBu) were investigated in detail. According to variable-temp. (VT) NMR investigations, the reaction proceeds stepwise with the initial formation of aminophosphane adducts, which s ...
The phosphido-substituted triruthenium cluster Ru-3(CO)(9)(mu-H)(mu-PPh2) is shown to react with H-2 to form the trihydride cluster Ru-3(CO)(9)(H)(mu-H)(2)(mu-PPh2), which undergoes a number of re-arrangement reactions on heating to yield other phosphido-s ...
Quant. evidence for the existence of aromaticity involving the d orbitals of transition metals is provided for the first time. The doubly bridged square planar (D4h) coinage metal clusters (M4Li2, M = Cu (1), Ag (2), and Au (3)) are characterized as arom. ...
This paper is aimed at introducing the organometallic chemist to the fascinating area of organometallic pharmaceuticals. It commences by identifying the properties of organometallic (transition metal) compounds that lend themselves to medical applications. ...
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 ...
Several washing agents ( EDTA, CDTA, NTA, 8 HQS, Ti-EDTA- citrate, Ca2+, and H+) were tested for their ability to extract adsorbed metal from biological surfaces to distinguish between internalized and total cellular metal (Pb, Ni, Cd, Zn, and Cu) for a gr ...
The molecular complex [W(&3bond; CtBu)(CH(2)tBu)(3)], 1, reacts with SiO2-(700) to give as major species 2a, [(&3bond; SiO)W(CtBu)(CH(2)tBu)(2)], while a bisgrafted surface species 3a, [(&3bond; SiO)(2)W-(&3bond; CtBu)(CH(2)tBu)], is obtained on SiO2-(200) ...
The catalytic activity of Rh for the partial oxidn. of methane to syngas can be markedly affected by interfacing polycryst. Rh films with a dispersed TiO2 interlayer deposited on YSZ. High CO selectivity (near 97%) can be reached in wide range of CH4:O2 ra ...
