Excited States of Gold(I) Compounds, Luminescence and Gold‐Gold Bonding [PDF]
Metal-Based Drugs, 1994 It has long been established by Khan that the superoxide anion, , generates singlet oxygen, , during dismutation. Auranofin, gold‐phosphine thiols, β‐Carotene, and metal‐sulfur compounds can rapidly quench singlet O2. The quenching of the , which exists at 7752 cm-1 above the ground state triplet, may be due to the direct interaction of the singlet O2 ...

Gold(I) and Gold(III) Trifluoromethyl Derivatives
Chemistry – A European Journal, 2013 AbstractTrifluoromethylation of AuCl3 by using the Me3SiCF3/CsF system in THF and in the presence of [PPh4]Br proceeds with partial reduction, yielding a mixture of [PPh4][AuI(CF3)2] (1′) and [PPh4][AuIII(CF3)4] (2′) that can be adequately separated. An efficient method for the high‐yield synthesis of 1′ is also described.
