An element through the looking glass: Exploring the Au-C, Au-H and Au-O energy landscape [PDF]
, 2015 Gold, the archetypal “noble metal”, used to be considered of little interest in catalysis. It is now clear that this was a misconception, and a multitude of gold-catalysed transformations has been reported.

Biologically‐Active Gold(III) Complexes [PDF]
Metal-Based Drugs, 1998 A review is given of the background to and results of the succesful pharmacological testing of [AuX2(damp)] (X = Cl, OAc; damp = 2 − Me2NCH2C6H4) against a range of microbes, fungi and tumouts, culminating in in vivo xenografts of ZR‐1‐75. These are the first fully evaluated gold(III) complexes.
