ChemPhysChem [LASYROC]

Abstract Chalcogen bonds (ChBs) occur between molecules containing Lewis acidic chalcogen substituents and Lewis bases. Recently, ChB emerged as a pivotal interaction in solution-based applications such as anion recognition, anion transport and catalysis. However, before moving to applications, the involvement of ChB must be established in solution. In this Concept article, we provide a brief...[En savoir plus]

Soutenance de thèse de doctorat de Marie-Julie Tilly

Vendredi 20 octobre à 9h00 dans l’amphithéâtre du collège doctoral européen. Ces travaux de thèse portent sur des complexes de cuivre(II) à ligands redox non-innocents: trifluorométhylation de peptides et application comme sonde en RMN du fluor pour doser le Cu(II) en milieux biologiques. Ils ont été réalisés sous la direction du Pr. Marine Desage-El Murr, du Dr. Laurent Raibaut et du Pr. Peter...[En savoir plus]

Organometallics [SRCO / LCQ]

Abstract The present study details the synthesis and characterization of novel Zn(II)-based organocations of the type [IPr*-Zn-R]+ (IPr* = 1,3-bis[2,6-bis(diphenylmethyl)-4-methylphenyl]-1,3-dihydro-2H-imidazol-2-ylidene; R = alkyl, aryl) and their use in styrene, alkyne, and carbonyl hydrosilylation catalysis. The neutral IPr* adducts [IPr*-ZnR2] (1, R = Me; 2, R = Et; 3, R = Ph) were prepared...[En savoir plus]

Magnetochemistry [POMAN]

Abstract The weak intramolecular magnetic interactions within a series of CuII3 complexes based on the trinucleating 2,4,6-tris(di-2-pyridylamino)-1,3,5-triazine (dipyatriz) ligand were investigated via Electron Paramagnetic Resonance (EPR) spectroscopy. X- and Q-band EPR spectroscopy in powders and frozen solutions were recorded and the Q-band spectra were interpreted by a multispin Hamiltonian...[En savoir plus]

Dalton Transactions [BCB]

Abstract The chelator diacetyl-bis(N4-methylthiosemicarbazone) (ATSM) and its complexes with CuII and ZnII are becoming increasingly investigated for medical applications such as PET imaging for anti-tumour therapy and the treatment of amyotrophic lateral sclerosis. However, the solubility in water of both the ligand and the complexes presents certain limitations for in vitro studies. Moreover,...[En savoir plus]

Soutenance de thèse de doctorat de Maxime Hourtoule

Vendredi 29 septembre à 13h30 dans l’amphithéâtre du collège doctoral européen. Ces travaux qui portent sur la réactivité de N-allènamides activés : Synthèse de briques moléculaires azotées fluorées inédites ont été dirigés par le Dr. Laurence Miesch au sein de l'équipe SOPhy (UMR 7177).   [En savoir plus]

Science Advances [SOPhy]

Abstract Specialized metabolite (SM) diversification is a core process to plants’ adaptation to diverse ecological niches. Here, we implemented a computational mass spectrometry–based metabolomics approach to exploring SM diversification in tissues of 20 species covering Nicotiana phylogenetics sections. To markedly increase metabolite annotation, we created a large in silico fragmentation...[En savoir plus]
