N-methylation of amines with CO2/H2 to N-methylamines over non-noble metal catalysts is very interesting but remains challenging. Herein, we present an alcohol (e.g., ethanol) promoted strategy for N-methylation of anilines...

Heterogeneous Hydrogenation

Unsaturated compounds are very rapidly hydrogenated with nickel-boride catalyst P-2-Ni without solvent under mild conditions (70-85 °C and 10 bar). Turnover numbers UZ up to 90,000 and space-time-yields of 7440 mmol product per 1 and 1 mgA Nickel in one hour with a mean catalyst activity ā = 124 were observed. This hydrogenation catalyst has a power, which is in the same magnitude of very active noble metal catalysts.

Nitrogen Doped Carbon

Nitrogen–doped carbon-supported cobalt–molybdenum bimetallic catalysts are active for the hydrodeoxygenation of sulfoxides to sulfides under mild conditions, which is the first case of use of heterogeneous non-noble metal catalysts for the reaction.

Some additional data about properties and applicability of a styrene-divinylbenzene polymer catalyst containing acidic and redox functional groups are reported. It is shown that the catalysts of this type can be prepared reproducibly and exhibit catalytic properties comparable to the properties of noble metal catalysts.
