Cover Story: A new G-(H2L)-Pd heterogeneous catalyst for the Cu-free Sonogashira cross coupling reaction between iodobenzene and phenylacetylene has been prepared via a supramolecular self-assembly process consisting in the spontaneous adsorption, in water at room temperature, of a macrocyclic H2L ligand on graphene (G) (G + H2L = G-(H2L)), followed by decoration of the macrocycle with Pd2+ ions (G-(H2L) + Pd2+ = G-(H2L)-Pd) under the same mild conditions. G-(H2L)-Pd, shows an excellent conversion (90%) of reactants into diphenylacetylene under mild conditions (50 °C, water, aerobic atmosphere, 14 h). The catalyst proved to be reusable for at least four cycles, although decreasing yields down to 50% were observed. View this paper.
