Leaching of palladium species from Pd nanoparticles under C - C coupling conditions was observed for both Heck and Suzuki reactions by using a special membrane reactor. The membrane allows the passage of palladium atoms and ions, but not of species l

The advantages of combining heterogeneous catalysis and aryl chloride substrates for cross-coupling are introduced. A heterogeneous Pd/C catalyst is used for activating aryl bromides and electron withdrawing aryl chlorides via a one-pot 'domino' HALE

Copper nanoclusters catalyse the cross-coupling of alkynes and aryl halides to give the corresponding disubstituted alkynes. No palladium, ligand, or co-catalyst is needed, and products are isolated in good yields (80–85%) and high selectivity. The

Stable nanoclusters (approximately 2 nm in diameter) of copper, silver, gold, palladium, and ruthenium coated with hydrophobic coronas are easily trapped in self-assembled "soft crystal" hexagonal phase gels made of water and surfactants. The system'

Quantum dots (2–5 nm) of copper and copper/palladium mixtures are found to be good catalysts for Suzuki cross-coupling. The catalysts are applicable to a wide range of iodo- and bromoaryl substrates, and give moderate yields using chloroaryl substr

The advantages of bimetallic nanoparticles as C–C coupling catalysts are discussed, and a simple, bottom-up synthesis method of core–shell Ni–Pd clusters is presented. This method combines electrochemical and ‘wet chemical’ techniques, and

A simple experiment based on exclusion of Pd nanoclusters was used to identify the true catalytic species in cluster-catalyzed Heck cross-couplings. A special reactor was used in which two compartments are separated by a nanoporous membrane that allo

We show that polyelectrolyte shells may be perfect hosts and microreactors for catalysis. Using a layer-by-layer self-assembly process to form hollow polyelectrolyte capsules, we show that individual layers can be replaced by palladium and gold nanoc
