Catalytic hydrogen evolution and hydrogen oxidation by cobalt macrocyclic glyoxime and tetra-imine complexes

Cobalt complexes supported by diglyoxime ligands of the type Co(dmgBF2)2(CH3CN)2 and Co(dpgBF2)2(CH3CN2) (where dmgBF2 is difluoroboryldimethylglyoxime and dpgBF2 is difluoroboryldiphenylglyoxime), as well as cobalt complexes with 1;143;-tetraene-N4 (Tim) ...

Palladium-Catalyzed Desulfitative Mizoroki-Heck Coupling Reactions of Sulfonyl Chlorides with Olefins in a Nitrile-functionalized Ionic Liquid

Paul Joseph Dyson, Pierre Vogel, Zhaofu Fei, Dongbin Zhao, Chandra Mouleeswara Rao Volla

Aryl and alkenyl sulfonyl chlorides can be used in Heck-Mizoroki-type couplings with mono- and disubstituted olefins in a nitrile-functionalized ionic liquid, viz. [C3CNpy][Tf2N]. Advantages over previously reported methods include: (1) use of a cheap cat ...

Cooperative effect between iridium and platinum in the carbonylation of methanol to acetic acid

Gabor Laurenczy

The iodocarbonyl monomer [PtI2(CO)2] 7 promotes the iridium catalyzed carbonylation of methanol to acetic acid at low water contents. Studies based on low pressure or high pressure NMR and the use of labeled reactants were cond ...

Promoting Role of [PtI2(CO)]2 in the Iridium-Catalyzed Methanol Carbonylation to Acetic Acid and Its Interaction with Involved Iridium Species

Gabor Laurenczy

The catalytic activity of the iridium complexes involved in methanol carbonylation is significantly enhanced when the carbonyliodoplatinum dimer [PtI2(CO)]2 (10') is added to the reaction mixt. Under CO this complex readily affords th ...

Electrochemically Induced Oscillations of C2H4 Oxidation Over Thin Sputtered Rh Catalyst Films

Christos Comninellis, György Foti

The electrochem. promoted induction of self-sustained catalytic rate and potential oscillations during C2H4 oxidn. was studied over sputtered Rh thin (40 nm catalyst films interfaced with ZrO2 (8 mol% Y2O3)). The reaction rate oscillates simultaneously wit ...

Electrochemical promotion of ethylene oxidation over Rh catalyst thin films sputtered on YSZ and TiO2/YSZ supports

Christos Comninellis, György Foti

The effect of electrochem. promotion of catalysis or nonfaradaic electrochem. modification of catalytic activity or electropromotion was studied for the model reaction of ethylene oxidn. on sputter-coated Rh films. The thin (40 nm) Rh films were deposited ...

Chemical and electrochemical promotion of supported rhodium catalyst

Olena Baranova

The chemical and electrochemical promotion of highly dispersed nanofilm Rh catalysts (dispersion: about 10 %, film thickness: 40 nm) has been investigated for the first time. To this end Rh metal was sputter-deposited, either on a purely ionic conductor (8 ...

Palladium-catalyzed desulfitative Mizoroki-Heck couplings of sulfonyl chlorides with mono- and disubstituted olefins: Rhodium-catalyzed desulfitative heck-type reactions under phosphine- and base-free conditions

Pierre Vogel

New conditions have been found for the desulfitative Mizoroki-Heck arylation and trifluoromethylation of mono- and disubustituted olefins with arenesulfonyl and trifluoromethanesulfonyl chlorides. Thus (E)1,2-disubstituted alkenes with high stereoselectivi ...

Relation between potential and catalytic activity of rhodium in propylene combustion

Christos Comninellis, György Foti, Ivan Bolzonella

The relation between the catalyst potential and the catalytic performance has been investigated in the gas-phase combustion of propylene with oxygen over rhodium catalysts at 375 DegC. The rhodium catalyst, deposited on yttria-stabilized zirconia (YSZ) sol ...
