Ultra-small sugar-substituted N-heterocyclic carbene-protected palladium nanoparticles and catalytic activity

Ultra-small Pd nanoparticles (UNPs) represent a distinctive type of nanomaterial making them very attractive for a range of applications. Herein, chiral sugar-substituted N-heterocyclic carbenes (NHCs) with various lengths of alkyl chain (sugar-NHCs-nCnH2n+1) were first used to prepare water-soluble Pd@NHCs-sugar UNPs via an efficient ligand-exchange strategy, which can be handled under air and are stable over 10?months. The Pd@NHCs-sugar UNPs were highly monodisperse, with tunable core diameters from 1.7 to 2.1?nm, and an effect of the particle size on the N-substituted aliphatic chains was observed. To investigate the accessibility of the surface, the Pd@NHCs-sugar UNPs were studied as catalysts for C–C coupling reaction in eco-friendly ethanol aqueous solution without any precipitation of metallic Pd. The presence of the longest aliphatic group in the Pd@NHCs-sugar UNPs imparts to them the highest catalyst activity (turnover number and turnover frequency up to 196?000 and 3?920?000?h?1).

From the grafting of NHC-based Pd(II) complexes onto TiO2 to the in situ generation of Mott-Schottky heterojunctions: The boosting effect in the Suzuki-Miyaura reaction. Do the evolved Pd NPs act as reservoirs?

The assumption that the real active species involved in the Suzuki-Miyaura reaction are homogeneous, heterogeneous or both is often proposed. However a lack of characterization of the true catalytic entities and their monitoring makes assumptions somewhat elusive. Here, with the aim of getting new insights into the formation of active species in the Suzuki-Miyaura reaction, a family of palladium(II) complexes bearing bis(NHC) ligands was synthesized for immobilization at the surface of TiO2. The studies reveal that once the complexes are anchored onto TiO2, the mechanism governing the catalytic reaction is different from that observed for the non-anchored complexes. All complexes evolved to Pd NPs at the surface of TiO2 under reaction conditions and released Pd species in the liquid phase. Also, this reactivity was boosted by the in situ generation of Mott-Schottky heterojunctions, opening new routes towards the design of heterogenized catalysts for their further implementation in reverse-flow reactors.
