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 rapid and modular synthesis of the first bifunctional N-heterocyclic carbenes bearing a (thio)urea moiety as H-bond donor group was reported. Different analogues could be accessed in seven steps from cheap (S)-pyroglutamic acid in good overall yields ( ...
A series of lanthanide complexes [LnClx(bpy)y(H2O)z]Cl3-x(H2O)n(EtOH)m (Ln ) Eu, Gd, Tb; x ) 1, 2; y ) 1, 2; z ) 2-4) with different numbers of 2,2′-bipyridine (bpy), chloride ions, and water molecules in the inner coordination sphere were synthesized and ...
A series of lanthanide adducts with different amounts of 1,10-phenanthroline, chloride ions, and water molecules in the inner and outer coordination spheres are investigated with the aim of relating the chemical bonding pattern in the crystals to the lumin ...
The invention relates to new proteins called alkylcytosine transferases (ACTs) derived from O-alkylguanine-DNA alkyltransferase, and to substrates for ACTs specifically transferring a label to these ACTs and to fusion proteins comprising these. The subs ...
This thesis deals with the self-organization of individual building blocks, specifically organic molecules and metal atoms, into supramolecular structures on metal surfaces under ultra high vacuum conditions (UHV). Self-organization of supramolecular syste ...
This overview presents recent work on the coordination chemistry and catalytic activity of bis-phosphine ruthenium(II)-arene complexes, RuCl(PPh3)(PR3)(eta(6)-arene), carried out in the Laboratory of Organometallic and Medicinal Chemistry at the EPFL. ...
NiII complexes of the new pincer amidobis(amine) ligand are described. The Ni chloride complex catalyzes Kumada-Corriu-Tamao coupling of unactivated alkyl halides with alkyl Grignard reagents, as well as double C-C coupling of CH2Cl2 with alkyl Grignard re ...
Computations on the reaction of azetidin-2-one, N-sulfonate azetidin-2-one, and 3-formylamine-N-sulfonate azetidin-2-one with [Mo(OH)(eta(3)-C3H5)(CO) 2(N2C2H4)] were performed at the B3LYP/6-31 + G(d,p) (LANL2DZ for Mo augmented by f polarization function ...
This thesis encompasses work on the coordination chemistry and catalytic activity of half sandwich ruthenium(II)-arene phosphine complexes. The investigation of phosphine dissociation and association reactions of these complexes represents the unifying the ...
We report scanning tunneling microscopy observations on the formation of 2D Co-based coordination compounds on the reconstructed Au(111) surface. Preorganized arrays of Co bilayer islands are shown to be local reaction sites, which are consumed in the form ...
