Investigating active phase loss from supported ruthenium catalysts during supercritical water gasification

Frédéric Vogel, Mohamed Tarik, David Baudouin

Active phase loss mechanisms from Ru/AC catalysts were studied in continuous supercritical water gasification (SCWG) for the first time by analysing the Ru content in process water with low limit-of-detection time-resolved ICP-MS. Ru loss was investigated ...

Palladium-Catalyzed Carboamination of Allylic Alcohols Using a Trifluoroacetaldehyde-Derived Tether

Jérôme Waser, Bastian Antoine Rodolphe Claude Muriel, Ugo Jonathan Orcel

The selective palladium-catalyzed carboamination of allylic alcohols is reported on the basis of the use of an easily introduced trifluoroacetaldehyde-derived tether. Aminoalkynylation reactions were realized using alkynyl bromides and commercially availab ...

Carbon Dioxide Based N-Formylation of Amines Catalyzed by Fluoride and Hydroxide Anions

Paul Joseph Dyson, Felix Daniel Bobbink, Martin Hulla, Shoubhik Das

We described herein a simple approach for N-formylation with CO2 and hydrosilane reducing agents. Fluoride and hydroxide salts efficiently catalyzed the reaction, principally through activation of the hydrosilanes, which led to hydrosilane reactivities com ...

Homogenous catalytic hydrogenation of bicarbonate with water soluble aryl phosphine ligands

Paul Joseph Dyson, Gabor Laurenczy, Katerina Stefania Sordakis

The chemical transformation of CO2 and bicarbonates into useful products becomes increasingly impor- tant as the atmospheric CO2 level has reached 400 ppm. Here a small library of sulfonated aryl mono- phosphines and aryl diphosphines was tested as stabili ...

Hydrogen Production by Selective Dehydrogenation of HCOOH Catalyzed by Ru-Biaryl Sulfonated Phosphines in Aqueous Solution

Gabor Laurenczy, Katerina Stefania Sordakis

The selective dehydrogenation of aqueous solutions of HCOOH/HCOONa to H2 and CO2 gas mixtures has been investigated using RuCl3·3H2O as a homogeneous catalyst precursor in the presence of di␣erent monoaryl-biaryl or alkyl-biaryl phosphines and aryl diphosp ...

Synthesis, characterization and in vitro anticancer activity of highly cytotoxic trithiolato diruthenium complexes of the type [(eta(6)-p-(MeC6H4Pr)-Pr-i)(2)Ru-2(mu(2)-SR1)(2)(mu(2)-SR2)](+) containing different thiolato bridges

Paul Joseph Dyson, Catherine Marie Amélie Clavel

A series of cationic dinuclear p-cymene ruthenium complexes containing three thiolato bridges with different substituents at the sulfur atoms, (eta(6)-p-(MeC6H4Pr)-Pr-i)(2)Ru-2(mu(2)-SR1)(2)(mu(2)-SR2) (R-1 = CH2Ph, R-2 = Ph: 4; R-1 = CH2Ph, R-2 = p-( ...

Heterogeneous Silica-Supported Ruthenium Phosphine Catalysts for Selective Formic Acid Decomposition

Paul Joseph Dyson, Gabor Laurenczy, Weijia Gan

The water-soluble ruthenium(II)–mTPPTS complex (mTPPTS= meta-trisulfonated triphenylphosphine) efficiently catalyzes the generation of hydrogen from formic acid in aqueous solution. This catalyst has been immobilized in a hydrophilic silica sup- port to fa ...

Built-in 5-Aminooxazole as an Internal Activator of the Terminal Carboxylic Acid: An Alternative Access to Macrocyclodepsipeptides

Jieping Zhu

A conceptually novel macrolactonization technology is described. A strategically positioned 5-aminooxazole served as an internal traceless activator of the neighboring C-terminal carboxylic acid allowing the occurrence of macrolactonization under mild acid ...

Beyond Click-Chemistry: Transformation of Azides with Cyclopentadienyl Ruthenium Complexes

Rosario Scopelliti, Kay Severin, Julie Risse

The cyclopentadienyl Ru complexes CpRuCl(cod) (cod = 1,5-cyclooctadiene), CpRuCl(PPh3)2, and [CpRuCl2]2 (Cp = η5-1-methoxy-2,4-di-tert-butyl-3-neopentylcyclopentadienyl) are able to catalyze the decomposition of benzyl azides to give 1,3,5-triphenyl-2,4- ...
