Cover Story: Colloidal Pd nanoparticles capped with octanethiolate ligands show good regio- and stereoselectivity toward the mono-hydrogenation of ester-conjugated allenes to either Z or E olefinic isomers depending on the substitution pattern around C=C bonds. Kinetic studies indicate that the reaction progresses through the hydrogenation of less hindered C=C bond to produce internal Z olefinic isomers. The high selectivity of Pd nanoparticles averting an additional hydrogenation is steered from the controlled electronic and geometric properties of the Pd surface, which are the result of thiolate-induced partial poisoning and surface crowding, respectively.
