The lithium enolate of (-)-6-endo-chloro-5-exo-(phenyl-seleno)-7-oxabicyclo[2.2.1]heptan-2-one ((-)-4) added to (+)-(3aR, 4aR,7aR,7bS)-3a,4a,7a,7b-tetrahydro-6,6-dimethyl[1,3]dioxolo[4,5]furo[2, 3-d]isoxazole-3-carbaldehyde ((+)-5) giving a major aldol (+) ...
The solubility of hydrogen and the corresponding Henry coefficients for 11 ionic liquids have been determined in situ at 100 atm H-2 pressure and are much lower than expected; attempts to correlate the solubility of hydrogen in the ionic liquids with the r ...
CO2 hydrogenation over catalysts is a potentially exciting method to produce fuels while closing the CO2 cycle and mitigating global warming. The mechanism of this process has been controversial due to the difficulty in clearly identifying the species pres ...
This work reports the hydrogenation of carbon dioxide/inorganic carbonate salts to formic acid/formate in two phase systems comprising an ionic phase, in which the catalyst is immobilized, and an aqueous phase in which the carbonates and formate are confin ...
Optimal conditions for chlorotris(triphenylphosphine)rhodium(I) (Wilkinson's catalyst) catalyzed selective satn. of a double bond in the presence of a nitro function are developed. Aryl iodide and benzyl ether are also tolerated under these hydrogenation c ...
A study was made of the effect of the frequency and intensity of the gas oscillations on mass transfer between a gas and a solid surface, under conditions of a linear oscillation direction and a precisely defined surface shape, for the purpose of obtaining ...

NOVELTY - A 2-butene-1,4-diol is prepared by hydrogenating 2-butyne-1,4-diol in the presence of a structured catalyst and in the absence of a solvent. USE - For preparing 2-butene-2,4-diol that is an important industrial intermediate in the preparation of ...
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; ...
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 ...
