Regioselective rearrangement of 7-azabicyclo[2.2.1]hept-2-aminyl radicals: first synthesis of 2,8-diazabicyclo[3.2.1]oct-2-enes and their conversion into 5-(2-aminoethyl)-2,3,4-trihydroxypyrrolidines, new inhibitors of alpha-mannosidases
Enantiomerically pure 2,8-diazabicyclo[3.2.1]oct-2-ene derivatives (+)-5 and (-)-5 have been obtained from 2-azido-3-tosyl-7-azabicyclo[2.2.1]heptanes (+)-1 and (-)-2 and their enantiomers, by ring expansion under radical conditions. Compounds (+)-5 and (- ...
2003Electrochemical preparation of peroxodisulfuric acid using boron doped diamond thin film electrodes
Christos Comninellis, Pierre-Alain Michaud
The authors have studied the electrochem. oxidn. of H2SO4 on B-doped synthetic diamond electrodes (BDD) obtained by hot filament CVD on p-Si. High current efficiency for H2SO4 oxidn. to peroxodisulfuric acid can be achieved in concd. H2SO4 (>2M) at moderat ...
2002Electro-combustion of polyacrylates with boron-doped diamond anodes
Christos Comninellis, Pierre-Alain Michaud
The electro-combustion of water sol. polymeric contaminants such as polyacrylates (PA) in aq. acid soln. using a B-doped diamond anode was studied by bulk electrolysis in 1 mol/dm3 HClO4 under galvanostatic conditions in a wide range of PA concns. and curr ...
2002Conjugate addition reactions combined with free-radical cross-linking for the design of materials for tissue engineering
PEG-diacrylamide was synthesized and utilized to make materials for tissue engineering. Acrylamide groups readily react with thiol groups, and peptides containing a single thiol group were coupled to the PEG-diacrylamide in aqueous solution at room tempera ...
2001Polymer reaction engineering at EPFL
A review, with 17 refs., on research carried out by the polymer reaction engineering group at EPFL in reaction engineering, including kinetic modeling of polymn. reactions (lab. and pilot scale reactors), free radical, polyepoxydation, polycondensation. De ...
2001Diffusion-limited reactive wetting: Spreading of Cu-Sn-Ti alloys on vitreous carbon
When wetting is promoted by interfaces, the rate at which the liquid spreads over the solid substrate is controlled by the rate at which the well-wetted interfacial product can be formed along the liquid/solid/atmospheric triple line. If this reaction invo ...
2001Synthesis and 13C NMR study of the triangulo-clusters [Pt3(m-CO)3-n(m-SO2)n(PR3)3] (n = 0-3)
Gabor Laurenczy, Raymond Roulet
[Pt-3(mu-CO)(3)(PPh3)(3)] was prepared in high yield by the reaction of [Pt-3(mu-CO)(3)(PPh3)(4)] with H2O2. The carbonyl ligands in [Pt-3(mu-CO)(3)(PR3)(3)] (PR3 = PPh3, PPh(2)Bz, PCy3, P'Pr-3) may be completely replaced by sulfur dioxide to give [Pt-3(mu ...
2000Degradation kinetics of atrazine and its degradation products with ozone and OH radicals: A predictive tool for drinking water treatment
The present study investigates the degradation of atrazine (2-chloro-4-(ethylamino)-6-isopropylamino-s-triazine) by ozone and OH radicals during ozonation and advanced oxidation processes, with the identification of the main degradation products. Besides t ...

2000Modelling full-scale advanced micropollutant oxidation
Advanced oxidation has proven to be an efficient process to increase micropollutant removal compared to conventional ozonation and to lower considerably the load to subsequent activated carbon treatment. Laboratory tests to determine the most important rea ...
