Leaching from Palladium Nanoparticles in an Ionic Liquid Leads to the Formation of Ionic Monometallic Species

Paul Joseph Dyson

Molecular dynamics simulations and DFT calculations suggest that leaching of palladium species from Pd nanoparticles in ionic liquids does not involve "naked" Pd(0) atoms or neutral ArPdX species formed by oxidative addition of arylhalides. Instead, the io ...

Copper-Catalyzed Three-Component Carboazidation of Alkenes with Acetonitrile and Sodium Azide

Qian Wang, Jieping Zhu, Ala Bunescu, Minh Tu Ha

A copper-catalyzed three-component reaction of alkenes, acetonitrile, and sodium azide afforded gamma-azido alkyl nitriles by formation of one C(sp3)-C(sp3) bond and one C(sp3)-N bond. The transformation allows concomitant introduction of two highly versat ...

Ligand and Metal Based Multielectron Redox Chemistry of Cobalt Supported by Tetradentate Schiff Bases

Rosario Scopelliti, Marinella Mazzanti, Julie Renée Michelle Andrez

We have investigated the influence of bound cations on the reduction of cobalt complexes of redox active ligands and explored the reactivity of reduced species with CO2. The one electron reduction of [CoII(Rsalophen)] with alkali metals (M = Li, Na, K) lea ...

Advanced Nanopowder Synthesis : Characterization, Performance and Kinetics of CeO2-based Supports, Catalysts and Segregation Processes

Frank Pilger

CeO2-based nanomaterials and their rich redox chemistry provide a possible route to pollutant abatement in various heterogeneous processes, and are in particular used as sorbents for flue gases and as oxygen promoters in three-way catalytic converters. The ...

Cu-decorated Raschig-TiO2 rings inducing MB repetitive discoloration without release of Cu-ions under solar light

César Pulgarin, Michaël Bensimon, Juan Kiwi, Rosendo Sanjines, Laura Victoria Suárez Murillo, Helena Luisa Teixido Pedarros

The methylene blue (MB) discoloration on innovative photocatalysts made up of Raschig-rings coated by pre-formed TiO2 nanoparticles decorated with CuOx (RR@TiO2-Cu) is presented. The MB-discoloration was drastically accelerated by the subsequent addition o ...

Synthesis of Oxazolidin-2-ones by Oxidative Coupling of Isonitriles, Phenyl Vinyl Selenone, and Water

Qian Wang, Jieping Zhu, Thomas Bertrand Pascal Marie Buyck, Delphine Pasche

Reaction of alkyl isocyanides, phenyl vinyl selenone, and water in the presence of a catalytic amount of Cs2CO3 afforded oxazolidin-2-ones in good yields. This unprecedented heteroannulation process created four chemical bonds in a single operation with th ...

Rh(III)-Catalyzed C-H Functionalizations as Strategies for Versatile Organic Building Blocks

Van Manh Pham

Transition-metal catalyzed C-H functionalizations have impacted and changed synthetic approaches towards the construction of relevant complex molecules, comprising natural products, active pharmaceutical ingredients, and organic materials. This thesis desc ...

Why are sec-alkylperoxyl bimolecular self-reactions orders of magnitude faster than the analogous reactions of tert-alkylperoxyls? The unanticipated role of CH hydrogen bond donation

Ganna Gryn'ova

High-level ab initio calculations are used to identify the mechanism of secondary (and primary) alkylperoxyl radical termination and explain why their reactions are much faster than their tertiary counterparts. Contrary to existing literature, the decompos ...

Suzuki-Miyaura cross-coupling of non-activated alkyl halides catalyzed by well-defined nickel pincer complexes

Thomas Clément Di Franco

Metal-catalyzed cross-coupling reactions are powerful and widespread methods for the carbon-carbon bond formation. Among the electrophile partners, non-activated alkyl halides remain challenging substrates because of their reluctance towards oxidative addi ...
