A Viable Hydrogen Storage and Release System Based on Cesium Formate and Bicarbonate Salts: Mechanistic Insights into the Hydrogen Release Step

Gabor Laurenczy, Katerina Stefania Sordakis, Andrew Francis Dalebrook

Aqueous solutions of cesium formate and bicarbonate repre- sent an effective hydrogen storage–delivery couple that under- goes either release or take up of hydrogen in the presence of {RuCl2(mTPPTS)2}2 (TPPTS = triphenylphosphine trisulfonate) and excess m ...

A novel platinum nanocatalyst for the oxidation of 5-Hydroxymethylfurfural into 2,5-Furandicarboxylic acid under mild conditions

Paul Joseph Dyson, Duncan Thomas Lindsay Alexander, Gabor Laurenczy, Zhaofu Fei, Ning Yan, Georgios Savoglidis, Sviatlana Siankevich

5-Hydroxymethylfurfural (HMF) is a key intermediate obtainable from various cellulosic (biomass) derivatives, but it must be converted to other chemicals such as 2,5-Furandicarboxylic acid (FDCA) for direct use. FDCA is an important derivative of HMF as it ...

Homogeneous Catalytic Dehydrogenation of Formic Acid: Progress Towards a Hydrogen-Based Economy

Paul Joseph Dyson, Gabor Laurenczy

One of the limiting factors to a hydrogen-based economy is associated with the problems storing hydrogen. Many different approaches are under evaluation and the optimum approach will not be the same for all applications, i.e., static, mobile, small and lar ...

Enhanced Conversion of Carbohydrates to the Platform Chemical 5-Hydroxymethylfurfural Using Designer Ionic Liquids

Paul Joseph Dyson, Rosario Scopelliti, Gabor Laurenczy, Zhaofu Fei, Ning Yan, Sviatlana Siankevich

5-Hydroxymethylfurfural (HMF) is a key platform chemical that may be obtained from various cellulosic (biomass) derivatives. Previously, it has been shown that ionic liquids (ILs) facilitate the catalytic conversion of glucose into HMF. Herein, we demonstr ...

Amide bond formation via C(sp(3))-H bond functionalization and CO insertion

Paul Joseph Dyson, Gabor Laurenczy, Ning Yan, Huizhen Liu

An efficient method for the synthesis of amides via Pd-catalyzed oxidative carbonylation of C(sp(3))-H bonds with CO and amines is described. The route efficiently provides substituted phenyl amides from alkanes. ...

Electrostatic and Non-covalent Interactions in Dicationic Imidazolium-Sulfonium Salts with Mixed Anions

Paul Joseph Dyson, Rosario Scopelliti, Gabor Laurenczy, Zhaofu Fei, Ning Yan

A series of thioether-functionalised imidazolium salts have been prepared and characterized. Subsequent reaction of the thioether-functionalised imidazolium salts with iodomethane affords imidazolium-sulfonium salts composed of doubly charged cations and t ...

Chemical Equilibria in Formic Acid/Amine-CO2 Cycles under Isochoric Conditions using a Ruthenium(II) 1,2-Bis(diphenylphosphino)ethane Catalyst

Gabor Laurenczy, Katerina Stefania Sordakis, Matthias Beller

The equilibrium position in formic acid/amine–CO2 systems has been examined as a function of pressure and tem- perature under isochoric conditions. The homogeneous ruthe- nium(II)-1,2-bis(diphenylphosphino)ethane catalyst was active in both reactions, that ...

Formic Acid Dehydrogenation Catalysed by Tris(TPPTS) Ruthenium Species: Mechanism of the Initial "Fast" Cycle

Gabor Laurenczy, Andrew Francis Dalebrook, Arnaud Thevenon, Ewan Patrick Frost-Pennington

Water-soluble ruthenium m-triphenylphosphinetrisulfonate (TPPTS) complexes are excellent catalysts for formic acid dehydrogenation. Interestingly, the choice of metal catalyst precursor has a direct influence on initial activities. The reaction with hexaaq ...

Metal-Free Catalyst for the Chemoselective Methylation of Amines Using Carbon Dioxide as a Carbon Source

Paul Joseph Dyson, Gabor Laurenczy, Felix Daniel Bobbink, Shoubhik Das

N-methylation of amines is an important step in the synthesis of many pharmaceuticals and has been widely applied in the preparation of other key intermediates and chemicals. Therefore, the development of efficient methylation methods has attracted conside ...
