Catalysis Today, 2005
The recent interest in gold catalysis provides the focus for this perspectives paper. Until recently gold has been overlooked as a key component of both homogeneous and heterogeneous catalysts. Two observations in the 1980s showed that gold could be a catalyst of choice, but it is only relatively recently that gold has been shown to be a very versatile

Gold Catalysis in Micellar Systems
Angewandte Chemie - International Edition, 2011The first examples are established for gold-catalyzed cycloisomerizations at room temperature in micellar systems using PTS or TPGS-750-M as the amphiphile.

Counterion Effects in Homogeneous Gold Catalysis
ACS Catalysis, 2015 Homogeneous gold catalysis has received growing attention over the past few years, enabling the replacement of consolidated organic reactions with more simple, selective, and chemically sustainable alternatives.

Chemical Society Reviews, 2021
This review summarizes the recent achievements of dinuclear gold-catalyzed redox coupling, asymmetric catalysis and photocatalysis. The dinuclear gold catalysts show a better catalytic performance than the mononuclear gold catalysts in certain cases.

Gold Catalysis: On the Phenol Synthesis
Organic Letters, 2001[reaction--see text] For the gold-catalyzed phenol synthesis an intramolecular migration of the oxygen atom was proven. Several other late transition metals with d(8) configuration allow this conversion, providing evidence for Au(III) being a catalytically active species.

Accounts of Chemical Research, 2014
For more than a decade the innovative field of homogeneous catalysis by gold was dominated by the interaction of the substrate molecule with one gold center, in most cases in mononuclear gold complexes. The initial interaction was typically a π-coordination of a carbon-carbon double bond to the gold, an activation of the unsaturated substrate molecule ...

Heterocycles from gold catalysis
Chemical Communications, 2011The article reviews the most important developments in the synthesis of heterocycles by gold catalysts for reactions directly involving the heteroatoms in the reacting groups. Reactions without direct participation of the hetero atoms, for example in substrates with the heteroatom in a tether between the reacting groups, are not included.
