Thiol-Ene Click Chemistry as a Tool for a Novel Family of Polymeric Ionic Liquids
Functionalized pyrrolidinium compounds, 3-((2-hydroxyethylthio)methyl)-1,1,4-trimethylpyrrolidinium and 3-((2-carboxyethylthio)methyl)-1,1,4-trimethylpyrrolidinium chlorides, are prepared from N,N-diallyl-N,N-dimethylammonium chloride by radical thiol-ene ...
2012Ruthenium-Catalyzed Synthesis of 1,5-Dichlorides by Sequential Intermolecular Kharasch Reactions
Rosario Scopelliti, Kay Severin, Aurélien Godinat, Katrin Anne Thommes, Charlotte Buron
Sequential intermolecular atom transfer radical addition reactions of activated dichlorides Cl2CRR′ (R = CN, CO2Et, R′ = H, CN, CO2Et) with two olefins catalyzed by [Cp*RuCl2(PPh3)] in the presence Mg allow the synthesis of linear 1,5-dichlorides. Differen ...
Wiley-Blackwell2011Side-Chain Peptide-Synthetic Polymer Conjugates via Tandem "Ester-Amide/Thiol-Ene" Post-Polymerization Modification of Poly(pentafluorophenyl methacrylate) Obtained Using ATRP
Harm-Anton Klok, Matthew Gibson, Maarten Danial
Herein the concept of tandem postpolymerization modification as a versatile route to synthesize well-defined, highly functionalized polymers is introduced. Poly(pentafluorophenyl methacrylate) obtained by atom transfer radical polymerization was first modi ...
2011Effect of Dissolved Organic Matter on the Transformation of Contaminants Induced by Excited Triplet States and the Hydroxyl Radical
Urs von Gunten, Silvio Canonica
Dissolved organic matter (DOM) has recently been shown to reduce the transformation rate of various aqueous organic contaminants submitted to oxidation by excited triplet states, apparently by inhibiting the transformation of oxidation intermediates. The m ...
2011Influence of Doping Level on the Electrochemical Oxidation of Formic Acid on Boron Doped Diamond Electrodes
Christos Comninellis, Stéphane Fierro
The influence of the boron doping level in boron doped diamond electrodes (BDD) on the electro-generation of active intermediates (hydroxyl radicals and hydrogen peroxide) involved in the oxidation of organic compounds has been studied. It is shown that th ...
2011Preparation of 5-Membered Rings via Radical Addition-Translocation-Cyclization (RATC) Processes Mediated by Diethyl Thiophosphites
A practical method for the formation of thiophosphonates bearing functionalized monocyclic, fused bicyclic and spirocyclic residues is presented. The procedure requires the easily available terminal alkynes as starting materials as well as commercially and ...
2011Palladium Alkynyl and Allenylidene Complexes: Very Efficient Precatalysts for C-C Coupling Reactions
Oxidative addition of BrC CC(=O)O-menthyl (1a) to [Pd(PPh3)(4)] affords the alkynyl complex trans-[Br(PPh3)(2)Pd-C CC(=O)O-menthyl] (2a). Subsequent reaction of 2a with trifluoroacetate gives trans-[(F3CCOO)(PPh3)(2)Pd-C CC(=O)O-menthyl] (3a). Reaction of ...
2011Synthesis of Unusual Oxime Ethers by Reaction of Tetranitromethane with B-Alkylcatecholboranes
The reaction of tetranitromethane with B-alkylcatecholboranes leads to the formation of unusual dinitrooxime ethers. A tentative mechanism is provided, which suggests the involvement of extremely fast addition of alkyl radicals to tetranitromethane. The su ...
2010Synthesis of Functional Polydepsipeptides via Direct Ring-Opening Polymerization and Post-Polymerization Modification
This contribution explores different strategies for the synthesis of side chain functional polydepsipeptides. First, the ring-opening polymerization of side chain functional morpholine-2,5-diones is revisited and the optimized reaction conditions used for ...
2010Oxidative transformation of micropollutants during municipal wastewater treatment: Comparison of kinetic aspects of selective (chlorine, chlorine dioxide, ferrate(VI), and ozone) and non-selective oxidants (hydroxyl radical)
Chemical oxidation processes have been widely applied to water treatment and may serve as a tool to minimize the release of micropollutants (e g pharmaceuticals and endocrine disruptors) from municipal wastewater effluents into the aquatic environment The ...
