Kinetics of the solvent-free hydrogenation of 2-methyl-3-butyn-2-ol over a structured Pd-based catalyst

Albert Renken, Lioubov Kiwi, Rocio Micaela Crespo Quesada, Martin Grasemann

The solvent-free selective hydrogenation of 2-methyl-3-butyn-2-ol (MBY) to 2-methyl-3-buten-2-ol (MBE) was studied over a Pd/ZnO structured catalyst and compared to its behavior in water-assisted conditions. The catalytic behavior was correlated with the s ...

Nitrogen fixation at passivated Fe nanoclusters supported by an oxide surface: Identification of viable reaction routes using density functional calculations

Alfredo Pasquarello, Harald Brune, Zeljko Sljivancanin

Using density-functional calculations, we investigate the possibility of ammonia synthesis at supported Fe nanoclusters along catalytic routes closely resembling those in biological nitrogen fixation. To achieve similar catalytic conditions as at the activ ...

Bronsted Acid Catalyzed Enantioselective Three-Component Reaction Involving the alpha Addition of Isocyanides to Imines

Jieping Zhu

That a chiral phosphoric acid is able to catalyze the three-component reaction of aldehydes, anilines, and alpha -isocyanoacetamides, leading to 2-(1-aminoalkyl)-5-aminooxazoles in excellent yields and moderate to good enantioselectivities, was reported. [ ...

Carbon dioxide hydrogenation on Ni(110)

Alfonso Baldereschi

We demonstrate that the key step for the reaction of CO2 with hydrogen on Ni(110) is a change of the activated molecule coordination to the metal surface. At 90 K, CO2 is negatively charged and chemically bonded via the carbon atom. When the temperature is ...
