Enantioselective hydrogenation of α,β-unsaturated carboxylic acid over cinchonidine-modified Pd nanoparticles confined in carbon nanotubes

The enantioselective hydrogenation of α,β-unsaturated acid catalyzed by Pd nanoparticles inside the channels of carbon nanotubes (CNTs) was reported. The Pd nanocatalyst inside the channels shows higher activity and enantioselectivity than that of Pd nanocatalyst outside the channels.101
