Promotional Effect of Ni in the Selective Gas-Phase Hydrogenation of Chloronitrobenzene over Cu-based Catalysts

Lioubov Kiwi, Javier Perez-Ramirez, Fernando Cardenas Lizana

We present 100?% selectivity to p-chloroaniline through the continuous gas-phase (atmospheric pressure; T=393523 K) catalytic hydrogenation of p-chloronitrobenzene over an activated Cu?Al (molar Cu/Al ratio 3:1) hydrotalcite. The synthesis by continuous co ...

Au/Mo2N as a new catalyst formulation for the hydrogenation of p-chloronitrobenzene in both liquid and gas phases

Lioubov Kiwi, Fernando Cardenas Lizana, Daniel André Samuel Lamey

The batch liquid phase hydrogenation of p-chloronitrobenzene over MO2N resulted in the sole formation of p-chloroaniline. Incorporation of Au nanoparticles (mean size = 8 nm) enhanced hydrogen uptake with a fourfold increase in rate, retention of ultrasele ...

Interfacial Photoreduction of Supercritical CO2 by an Aqueous Catalyst

Hubert Girault, Manuel Alejandro Méndez Agudelo, Patrick Voyame

Not just a solvent anymore: CO2 reduction under supercritical conditions was achieved in a biphasic water–supercritical CO2 system using an aqueous soluble catalyst (see picture). The introduction of such an interface provides a suitable reaction medium wh ...

Hydrogen Storage in Formic Acid – Amine Adducts

Gabor Laurenczy, Matthias Beller

Formic acid, containing 4.4 wt% of hydrogen, is a non-toxic liquid at ambient temperature and therefore an ideal candidate as potential hydrogen storage material. Formic acid can be generated via catalytic hydrogenation of CO2 or bicarbonate in the presenc ...

Cyclometalated Iridium(III) Complexes Based on Phenyl-Imidazole Ligand

Michael Graetzel, Mohammad Khaja Nazeeruddin, Rosario Scopelliti, Filippo de Angelis, Xiaoyu Zhang

Phenyl-imidazole-based ligands with various substitution patterns have been used as the main ligand for heteroleptic bis-cyclometalated Iridium complexes. Two series of complexes have been prepared and their photophysical and electrochemical properties wer ...

Rhodium-Catalyzed C-C Bond Cleavage: Construction of Acyclic Methyl Substituted Quaternary Stereogenic Centers

Nicolai Cramer

A rhodium-catalyzed enantioselective insertion into the C-C bond of tert-cyclobutanols and subsequent proto-demetalation provides access to Me substituted quaternary stereogenic centers in excellent yields and enantioselectivities. The reaction was used fo ...

Enantioselective rhodium-catalyzed C-C bond activations

Nicolai Cramer

A review. The catalytic activation of C-C single bonds represents a major challenge in organometallic chem. Strained ring substrates occupy in this respect a privileged role as their inherent ring strain facilitates the desired metal insertion. Employing s ...
