Recent Findings in Fullerenes Described by Researchers from University of Alicante (Non-covalent immobilization of RhDuphos on carbon nanotubes and carbon xerogels)

By a News Reporter-Staff News Editor at Science Letter -- A new study on Fullerenes is now available. According to news originating from Alicante, Spain, by NewsRx correspondents, research stated, "The immobilization of the chiral complex RhDuphos, by electrostatic or pi-pi (adsorption) interactions, on carbon nanotubes and carbon xerogels is investigated. To promote such interactions, the supports were either oxidized or heat treated to create carboxylic type surface groups or an apolar surface, respectively."

Our news journalists obtained a quote from the research from the University of Alicante, "The catalysts were tested in the hydrogenation of methyl 2-acetamidoacrylate. The prepared hybrid catalysts are less active than the homogeneous RhDuphos, but most of them show a high enantioselectivity and the one prepared with the oxidized carbon xerogel is also reusable, being able to give a high substrate conversion, keeping as well a high enantioselectivity. The anchorage by electrostatic interactions is more interesting than the anchorage by pi-pi interactions, as the pi-pi adsorption method produces a modification of the metal complex structure leading to an active hybrid catalyst but without enantioselectivity."

According to the news editors, the research concluded: "The creation of carboxylic groups on the support surface has led to some hindering of the complex leaching."
