Amatoxins are ribosomally synthesized and post-translationally modified bicyclic octapeptides biosynthesized by the deadly basidiomycete fungus Amanita phalloides. Amongst this group, alpha-amanitin is the most widely known toxin and is currently under inv ...
Liquid-phase hydrodeoxygenation of phenol over silica-supported MoOx-ReOx catalysts was investigated at 300 degrees C and 5 MPa of H-2. Mixed-oxides catalysts with similar surface metal density (2.3 atoms of metal per nm(2) of SiO2) but different relative ...
Chemical recycling of plastics provides more flexibility for materials circulation than landfill disposal or incineration. Intensive research efforts have been devoted to maximizing the efficiency of chemical recycling through catalyst development. The fro ...
Helium nanodroplets are liquid, finite size, nanoscale helium clusters that have been employed since the 1990s as a matrix for high-resolution spectroscopy of molecules. Spectroscopic studies of ionic species inside helium droplets were not however realise ...
The use of tethers allows to overcome reactivity and selectivity issues often encountered with intermolecular reactions. Although tethers have been successfully applied for decades, their installation and removal usually requires additional steps. This min ...
Alkene functionality can be found in the majority of natural products, drugs, catalysts and organic materials. Therefore, methods of C-C double bond formation constitute a cornerstone of organic synthesis. Selective formation of either (Z)- or (E)-isomer i ...
We report the fabrication of spherical superstructures composed of SiO2 and TiO2 nanoparticles and their applications in catalyzing organic reactions. Assembling of the nanoparticles into superstructures is done by heating a water-in-oil micro-emulsion, wh ...
Reduction of CO2 by electrochemical and photoelectrochemical methods to produce carbon-rich fuels is a heavily pursued research theme. Most of the current efforts are focused on the development of transition-metal-based catalysts. In this tutorial review, ...
Palladium-catalyzed stereoselective arylative ring-opening reaction of norbornenol derivs. was studied. In presence of aryl bromides, corresponding cyclohexene derivs. were obtained in good yields. Meanwhile, reaction with bromoanilines yielded quinolines ...
Unsymmetrical cationic [4] helicenes react with hydride or organolithium reagents and the two diastereotopic faces can be discriminated with high efficiency (dr up to and higher than 49 : 1) ...
