This catalyst has been used for the hydrogenation of alkenes and alkynes under mild conditions. Quantitative studies on the rates of hydrogenation of selected substrates are reported with the mechanisms being discussed. Data on the high recycling efficiency of the catalyst as well as solvent effects ...

was achieved within 80 min at the catalyst/substrate molar ratio of 1:2000. It should be noted that the catalytic performance of the PdCu@Cu2O (Cu/Pd = 1:1) catalyst was far superior to that of the commercial Lindlar catalyst (Supplementary Fig.8). Moreover, the catalyst exhibited...
At the oil–water interface, electroreduction of protons from the aqueous electrolyte over Pd nanoparticles enables the ECH of water-insoluble alkenes present in the organic phase within emulsion droplets. Full size image In this context, we report here the application of Pickering emulsions as a ...
Herein, we report the findings of a study investigating the transfer of alkyne semi-hydrogenation over a bimetallic catalyst, in which Pd nanoparticles and highly dispersed Ni atoms were anchored onto graphite-like C3N4 with nitrogen defects. The optimal Pd0.14Ni0.01 catalyst was used for ...
Intermolecular Hydroamination of Ethylene and 1-Alkenes with Cyclic Ureas Catalyzed by Achiral and Chiral Gold(I) Complexes The intermolecular hydroamination of unactivated alkenes remains an important, unsolved challenge in catalysis. This transformation has been realized with ... Z Zhang,SD Lee,RA Wid...

The design of high-performance, mild-condition HDO catalysts is a crucial step in the high-value utilization of the conversion of phenol to cyclohexanone. In this paper, the effect of modifier on the catalyst activity was investigated by surface modification of ZrO2 support by ascorbic acid (AA...
(Fig.5d, e). Based on the excellent performance of Co/BPE in the above reaction, we carried out the gram-scale asymmetric hydrogenation of AA (artemisinic acid)5in the presence of 0.5 mol% of chiral cobalt catalyst. Desired product (R)-DHAA (dihydroartemisinic acid)6was obtained in...
