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.
Linear amides, prepd. in one step by the Ugi four-component reaction, were converted to 3,4-dihydroquinoxalin-3-ones or to 2-(2-oxoindolin-1-yl)acetamides dependent on the catalytic conditions. While microwave irradn. was found to be determinant on the rea ...
Polyvinylpyrrolidone stabilized rhodium nanoparticles are highly sol. in hydroxyl-functionalized ionic liqs., providing an effective and highly stable catalytic system. In hydrogenation reactions, excellent results were obtained, and transmission electron ...
A novel composite material based on carbon nanofibers (CNF) grown on sintered metal fibers (SMFInconel) filter was investigated for its favorable properties as catalytic support. The CNF were formed directly over the SMFInconel by thermal (650 degrees C) c ...
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 ...
N-allyloxycarbonyl group could be efficiently removed using sodium borohydride as hydride donor in the presence of catalytic amount of palladium (0). The conditions were applied to chemoselective protecting group transformation (transprotection) and peptid ...
Real-world vanadium-based catalysts for the selective catalytic reduction (SCR) of NO with NH3 are occasionally exposed to high temperatures, which can induce catalyst aging. In this work, a 2.0 wt% V2O5/WO3-TiO2 catalyst based on commercial WO3-TiO2 was l ...
The Diels-Alder adduct 3 of 2,2'-ethylidenebis(3,5-dimethylfuran) to diethyl (E,E)-4-oxohepta-2,5-diene-1,7-dioate was converted into meso-(1R,2R,4R,4aR,5S,7S,8S,8aS,9aS,10aS)- 1,8-bis(acetoxymethyl)- 1,3,4,5,6,7,8,8a,9,9a-decahydro-2,4,5,7,10 -pentamethyl ...
