Organic & Biomolecular Chemistry [LCSOM]

Abstract: Organofluorines have a broad range of industrial applications, such as pharmaceutics, liquid crystal displays (LCD), solar cells, textiles, and construction coatings, and are used in peptidomimetics, surfactants, refrigerants, anesthetics, and agrochemicals. Among them are versatile monofluoroalkenes that play a crucial role in medicinal and synthetic chemistry. The synthetic...[En savoir plus]

J. Org. Chem. [SOPhy]

Abstract : A method for the construction of trifluorinated-5-methylenepyrrolidinone is reported. This strategy combines an acid-catalyzed two-carbon homologation process between ynamides and aldehydes, providing CF3-substituted dienes followed by a metal-free domino hydroamination/isomerization/transamidation sequence, delivering trifluorinated-5-methylenepyrrolidinone...[En savoir plus]

Chem. Eur. J./ Cover [POMAM]

Graphical Abstract An asymmetric diradical was synthesized by grafting a nitroxide radical onto the [Y(Pc)2]⋅ radical system. The molecule was shown to exhibit a weak exchange interaction between its two radical units. The g-asymmetry combined with the magnetic interaction led to the electron paramagnetic resonance transition of different tipping angles, which could be selectively enhanced by...[En savoir plus]

Nanoscale [CLIC]

Abstract: The controlled growth of self-assembled networks on surfaces based on viologen salts is a major scientific challenge due to their unique electronic properties. The combination of solid-state NMR spectroscopy and atomic force microscopy at ambient conditions can unravel the fine organization of the supramolecular network on a graphitic surface by positioning the counter-ions relative to...[En savoir plus]

Physical Review B [LCQ]

Abstract: This work merges two different types of many-electron ensembles, namely, the Theophilou-Gross-Oliveira-Kohn ensembles of ground and neutrally excited states, and the more recent 𝑁-centered ensembles of neutral and charged ground states. On that basis, an in-principle exact and general, so-called extended 𝑁-centered, ensemble density functional theory of charged and neutral electronic...[En savoir plus]

Coordination Chemistry Reviews [ECMC]

Summary: Rigid terdentate ‘pincer’ ligands containing a bridgehead N-heterocyclic carbene (NHC) donor attract considerable interest as spectators in transition metal complexes with broad scope and potential applications in the fields of catalysis, medicinal chemistry and material science. This review illustrates recent developments where the donor groups in the side-arms associated with the...[En savoir plus]

Chemistry an Asian Journal [ECMC/LCQ]

Summary : Pyridine Ring-Expanded dicarbene Pincer ligands were synthesized and some representative complexes with Ni and Cr show distinct geometrical and electronic characteristics from analogues with 5-membered ring heterocycles, opening new possibilities for pincer ligands featuring carbene donors. Abstract: The pincer complexes [NiIIBr(CNC)]Br (4), [CrIIIBr3(CNC)] (5 a) and...[En savoir plus]
