A golden opportunity: A mechanism has been proposed to account for the chemoselective hydrogenation of α,β-unsaturated ketones (or aldehydes) to unsaturated alcohols catalyzed by monodisperse Au25(SR)18 particles (see picture). Now that the structure of these nanoparticles is known, structure–activity correlations can be drawn.
