Poly(ethylene glycol) stabilized Co nanoparticles as highly active and selective catalysts for the Pauson–Khand reaction†
Abstract
PEG-stabilized cobalt nanoparticles were prepared by thermal decomoposition of [Co2(CO)8] in PEG and were shown to be highly active and selective catalysts, for intra- and intermolecular Pauson–Khand reactions (PKR), in organic solvents or aqueous media.
