Ligand-free, copper-free Sonogashira reaction and styrene hydrogenation catalyzed by 1-dodecanethiolate stabilized palladium nanoparticles

Ligand-free, copper-free Sonogashira coupling reaction and styrene hydrogenation catalysis by linear organic dodecanethiol stabilized palladium nanoparticles (PdTNPs) were studied. At 70 degrees C and in the presence of piperidine, PdTNPs catalysts for Sonogashira reaction of iodobenzene with phenyl acetylene afforded 90% yield in 10 min under air/nitrogen atmosphere. PdTNPs catalysts also exhibit high catalytic activity for the hydrogenation of styrene at room temperature with excellent yield and recyclability.
