Well-Defined Dinuclear Gold Complexes for Preorganization-Induced Selective Dual Gold Catalysis [PDF]

, 2016
The synthesis, reactivity, and potential of well‐defined dinuclear gold complexes as precursors for dual gold catalysis are explored. Using the preorganizing abilities of the ditopic PNHPiPr (LH) ligand, dinuclear AuI–AuI complex  1 and mixed‐valent AuI ...

Gold(I)-catalyzed 6-endo hydroxycyclization of 7-substituted-1,6-enynes

Beilstein Journal of Organic Chemistry, 2013
The cyclization of o-(alkynyl)-3-(methylbut-2-enyl)benzenes, 1,6-enynes having a condensed aromatic ring at C3–C4 positions, has been studied under the catalysis of cationic gold(I) complexes. The selective 6-endo-dig mode of cyclization observed for the

Catalysis by Gold Nanoparticles [PDF]

Gold Bulletin, 2002
Gold catalysts have superior activity in CO and other oxidations at low temperatures. Both a small (~ 5nm) particle size and the presence of a partly reducible oxide (ceria or a transition metal oxide) have a beneficial effect on the catalyst performance.

The impact of metal dopants on the properties of nZVI: a theoretical study

JPhys Materials
The substitution of Fe with metal dopants shows potential for enhancing the wastewater remediation performance of nanoscale zero-valent iron (nZVI). However, the specific roles and impacts of these dopants remain unclear.

Population and hierarchy of active species in gold iron oxide catalysts for carbon monoxide oxidation

Nature Communications, 2016
The identity of active species in supported gold catalysts for low-temperature carbon monoxide oxidation remains an open question. Here, the authors look at the catalytic behaviours of supported catalysts prepared under different conditions and correlate
