Significance

Copper nanoparticles supported on diamond nanoparticles (Cu/DH) catalyzed the hydrogenation of alkenes with N2H4·H2O to give the corresponding alkanes in 60–100% conversion with selectivities of the desired products from 96 to >99% (19 examples, eq. 1). The catalyst was recovered by centri­fugation and reused three times without significant loss of the catalytic activity in the hydrogenation of styrene (3th reuse: 94% conversion, >99% selectivity).

Comment

The authors previously reported the preparation of Cu/DH and their application to the aerobic oxidation of thiols (ChemCatChem 2013, 5, 241). The catalytic activity of Cu/DH was superior to that of copper nanoparticles supported on activated carbon, graphite, and multi-walled carbon nanotubes and gold and palladium nanoparticles supported on DH. Phenyl acetylene underwent the hydrogenation under similar conditions to give styrene and ethylbenzene (39% conversion; styrene/ethylbenzene = 61:39).
