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.
Dissolved organic matter (DOM) can act as a photosensitizer and an inhibitor in the phototransformation of several nitrogen-containing organic contaminants in surface waters. The present study was performed to select a probe molecule that is suitable to me ...
The chemical modification of polymers with lateral polar groups increases their dielectric permittivity above the glass transition temperature, making them attractive materials for dielectric elastomer actuators. Despite the large dipole moment of the sulf ...
The goal of this thesis was to find conditions to form C-C double bond and single bond using sulfonyl derivativies, which are arising from the Vogel's oxyallylation cascades. In a second chapter, it is shown that 2-methylprop-2-ene-1-sulfonyl fluorides can ...
The goal of this thesis is to develop new carbon-carbon bond forming reactions using inexpensive and simple coupling partners like aryl halides (pseudohalides), sulfonyl derivatives, Grignard reagents, alkenes and alkynes with metal catalysis, preferably u ...
The present invention concerns an intermediate of the following formula (I) in which R1 and R2 represent independently of each other a C1-C12 alkyl group, a (C1-C12 alkoxy)carbonyl group, optionally substituted by one, two or three halogen atom, a (C2-C12 ...
New conditions have been found for the desulfitative Mizoroki-Heck arylation and trifluoromethylation of mono- and disubustituted olefins with arenesulfonyl and trifluoromethanesulfonyl chlorides. Thus (E)1,2-disubstituted alkenes with high stereoselectivi ...
The ene reaction of sulfur dioxide with enoxysilanes or with allylsilanes generates silyl sulfinates that can be brominated (Br-2 or NBS) or chlorinated (NCS or Cl-2) to produce the corresponding sulfonyl halides. They react with primary and secondary amin ...
The goal of this thesis was to open a new route to the synthesis of conjugated trienes using a new SO2-based C-C bond forming reactions developed in Lausanne. In addition, the potential of SO2 for applications in synthetic organic chemistry has been exploi ...
Alk-2-enesulfonyl chlorides 1-4 were synthesized by the BCl3-promoted ene reaction of alkenes with SO2. These sulfonyl chlorides were then used as electrophilic partners in iron-catalyzed desulfinylative cross-coupling reactions with different Grignard rea ...
