Homogeneous hydrogenation of carbon dioxide and bicarbonate in aqueous solution catalyzed by water-soluble ruthenium(II) phosphine complexes

Gabor Laurenczy

The water-soluble Ru(II)-phosphine complex, [{RuCl2(mTPPMS)(2)}(2)] was found a suitable catalyst for the hydrogenation of NaHCO3 to NaHCO2 in aqueous solution under mild conditions with catalyst turnover frequencies (TOFs) in the range of 35-50 h(-1) at 5 ...

Tuning the properties of ruthenium bipyridine dyes for solar cells by substitution on the ligands-characterisation of bis[4,4'-di(2-(3-methoxyphenyl)ethenyl)-2,2'-bipyridine][4,4'-dicarboxy-2,2'-bipyridine]ruthenium(II) dihexafluorophosphate

Ulf Anders Hagfeldt

The new dye complex bis[4,4'-di(2-(3-methoxyphenyl)ethenyl)-2,2'-bipyridine][4,4'-dicarboxy-2,2'-bipyridine]ruthenium(II) dihexafluorophosphate (1) was prepd., characterized by absorption spectroscopy and adsorbed onto nanocryst. TiO2 electrodes. The resul ...

Aqueous organometallic catalysis. Isotope exchange reactions in H-2-D2O and D-2-H2O systems catalyzed by water-soluble Rh- and Ru-phosphine complexes

Gabor Laurenczy

The water-soluble complexes [{RuCl2(mTPPMS)(2)}(2)], [RuCl2(PTA)(4)], [RhCl(mTPPMS)(3)], [RhCl(mTPPTS)(3)], and [RhCl(PTA)(3)] (mTPPMS=sodium salt of meta-sulfonatophenyl-diphenylphosphine, mTPPTS=sodium salt oftris(meta-sulfonatophenyl) phosphine, and PTA ...

The effect of pH on the hydrogenation of benzene in an aqueous biphase using a ruthenium catalyst

Paul Joseph Dyson, Corinne Daguenet

There is currently much controversy surrounding homogeneous arene hydrogenation catalysis since it has been suggested that the active catalysts are actually heterogeneous. Since many of the proposed homogeneous catalysts operate in water under biphasic con ...

A comparison of ruthenium-catalysed arene hydrogenation reactions in water and 1-alkyl-3-methylimidazolium tetrafluoroborate ionic liquids

Paul Joseph Dyson, Gabor Laurenczy, William Henderson

The hydrogenation of benzene and other arene substrates under biphasic conditions is evaluated using the catalyst precursor Ru(eta(6)-C10H14)(pta)Cl-2 (pta = 1,3,5-triaza-7-phosphaadamantane) immobilised in water and 1-alkyl-3-methylimidazolium tetrafluoro ...

Conducting Polymers Containing In-Chain Metal Centers: Homogeneous Charge Transport through a Quaterthienyl-Bridged {Os(tpy)2} Polymer

Ulf Anders Hagfeldt

Electron transport in electrochem. polymd. films of a bithienyl-substituted {Os(tpy)2} complex has been studied. The voltammetric response assocd. with the Os2+/3+ process is unusually ideal under both semi-infinite linear and finite, diffusion conditions. ...

Dramatic pressure effects on the selectivity of the aqueous organic biphasic hydrogenation of trans-cinnamaldehyde catalvzed by water-soluble Ru(II)-tertiary phosphane complexes

Gabor Laurenczy

In a water/chlorobenzene biphasic reaction, the hydrogenation of trans-cinnamaldehyde, catalyzed by water-soluble Ru(II)-phosphane complexes at pH 3.04 (phosphate buffer), produces a 61:39 mixture of cinnamyl alcohol and dihydrocinnamaldehyde at 1 bar H-2; ...
