Reports Outline Heavy Metals Findings from University of Turin [Palladium nanoparticles supported on Smopex metal scavengers as catalyst for carbonylative Sonogashira reactions: Synthesis of alpha,beta-alkynyl ketones]

By a News Reporter-Staff News Editor at Science Letter -- Investigators discuss new findings in Heavy Metals. According to news reporting originating in Turin, Italy, by NewsRx journalists, research stated, "Palladium nanoparticles supported on two Smopex commercial metal scavengers (1% w/w) have been tested in the carbonylative Sonogashira reactions of aryl iodides with phenylacetylene. Their catalytic activity has been compared with those of more common catalysts (Pd/C, Pd/gamma-Al2O3)."

The news reporters obtained a quote from the research from the University of Turin, "Pd/Smopex -234 resulted especially effective in the synthesis of alkynyl ketones even working with a low amount of palladium (0.2-0.5 mol%). Preliminary heterogeneity tests (i.e. hot filtration test, Pd leaching and recycle of the catalyst) have been performed in order to evaluate the catalytic behaviour of this system."

According to the news reporters, the research concluded: "The obtained results seem to indicate that Pd/Smopex -234 could act as a truly heterogeneous catalyst."
