[EN] Ionic liquids are composed of an organic cation and a highly delocalized perfluorinated anion, which remain tight to each other and neutral across the extended liquid framework. Here we show that n-alkanes in millimolar ...
[EN] The assumption that oxidative addition is the key step during the cross-coupling reaction of aryl halides has led to the development of a plethora of increasingly complex metal catalysts, thereby obviating in many ...

[EN] Cyanosilylation of carbonylic compounds has a great interest in organic chemistry. In the present work
ketones cyanosilylation is performed catalyzed by cerium oxide in mild conditions. A kinetic study was
carried ...

[EN] The synthesis and reactivity of single metal atoms in a low-valence state bound to just water, rather than to organic ligands or surfaces, is a major experimental challenge. Herein, we show a gram-scale wet synthesis ...
[EN] Group 15 elements in zero oxidation state (P, As, Sb and Bi), also called pnictogens, are rarely used in catalysis due to the difficulties associated in preparing well-structured and stable materials. Here, we report ...

[EN] The use of bimetallic nanoparticles as catalysts in complex organic synthesis is rare, despite the widespread use of these materials in thermal C-1 chemistry and electrocatalysis. Here we show that intimate RuPt ...
[EN] The chemical bulk reductive covalent functionalization of thin-layer black phosphorus (BP) using BP intercalation compounds has been developed. Through effective reductive activation, covalent functionalization of the ...
