Chemistry : A European Journal

Copper-induced alkyne-azide cycloaddition (CuAAC), popularly known as the click-reaction, is one of the most widely used synthetic methods in the design of supramolecular scaffoldings. Whether its catalytic or stoichiometric version is concerned, the involvement of two metals in the cycloaddition has been debated in the literature in the case of copper and other metals such as zinc. Research...[En savoir plus]

Percée décisive dans le domaine de l’hydroformylation asymétrique

Metal confinement can make the difference, as shown by M. Jouffroy et al. in a recent Communication in Angew. Chem. . The use of cyclodextrin derivatives with an introverted PIII donor atom in the rhodium-catalyzed hydroformylation of styrene leads to high iso- and enantioselectivity. This is due to the selective formation of monophosphane complexes in which the cyclodextrin cavity tightly wraps...[En savoir plus]

European Journal of Inorganic Chemistry

CONFINING N-HETEROCYCLIC CARBENES N-heterocyclic carbene bearing two non-rotating alkylfluorenyl substituents are sterically not very crowded, but they can nevertheless be used to prepare remarkably fast Suzuki-Miyaura cross-coupling catalysts. Their efficiency relies on their ability to behave like a clamp that can permanently protect two trans-located coordination sites. See : M. Teci, E....[En savoir plus]

European Journal of Inorganic Chemistry

Special on Polyoxometallates   The front cover of the Special Issue of the European Journal of Inorganic Chemistry Special on Polyoxometalates shows (top left) a snapshot of a simulated box of water containing [AlW12O40]5- POM anions and their H3O+ counterions, forming local aggregates (zoomed). Indeed, the free energy profile ΔG(d) calculated as a function of the POM···POM distance in water...[En savoir plus]

Coordination Chemistry Reviews

February 2013 Metallated cavitands (calixarenes, resorcinarenes, cyclodextrins) with internal coordination sites. This article provides a comprehensive overview of transition metal complexes capable of directing the binding of exogeneous ligands inside a molecular cavity. Special emphasis is placed on the role of the cavity in supramolecular catalysis and metal-assisted molecular...[En savoir plus]

Nature Matérials

The cover of the December 2012 issue of Nature Materials shows supported lipid bilayers in which ‘Domains stack up’. The issue reports that in addition to intralayer smectic arrangement, supported stacks of multicomponent lipid bilayers with phase-separated domains can also display interlayer order, where domain alignment propagates across hundreds of bilayer. The team Membrane Biophyiscs and NMR...[En savoir plus]
