Enantioselective radical chemistry: a bright future ahead

open access: yesBeilstein Journal of Organic Chemistry
This perspective is focused on enantioselective free radical reactions. It describes several important catalytic asymmetric strategies applied to enantioselective radical reactions, including chiral Lewis acid catalysis, organocatalysis, photoredox ...

Highly selective hydrogenation of arenes using nanostructured ruthenium catalysts modified with a carbon–nitrogen matrix

open access: yesNature Communications, 2016
The selective reduction of arenes is important in organic synthesis and also valorization of biomass. Here, the authors report the use of ruthenium-based nanoparticles, which display high activity in arene reduction and preferentially hydrogenate ...

Deactivation and Regeneration of Mo/ZSM-5 Catalysts for Methane Dehydroaromatization

open access: yesEurasian Chemico-Technological Journal, 2010
The methane dehydroaromatization (DHA) was studied over a series of impregnated Mo/ZSM-5 catalysts with different molybdenum contents (1-10 wt.%). It was shown that total methane conversion was decreased by 30% during 12 h of DHA reaction.

Carbon in Catalysis [PDF]

open access: yes, 2013
Abstract This review is concerned with nanoscale carbon as a catalyst. Elemental carbon has become available in many nanostructured forms representing combinations of the hybridizations found in fundamental carbon allotropes, and the materials can be enriched by a large number of surface functional groups, some generated by nanostructuring ...

Ligand engineering to achieve enhanced ratiometric oxygen sensing in a silver cluster-based metal-organic framework

open access: yesNature Communications, 2020
Incorporating dual fluorescence and phosphorescence into a single matrix is attractive for oxygen sensing, but material design is challenging. Here the authors achieve dual fluorescence-phosphorescence from a single linker chromophore in a silver ...
