Abstract

The equilibria of stepwise substitution Au(bipy)+ OH– = Au(bipy)ClOH+ + Cl– and Au(bipy)+ 2OH– = Au(bipy)+ 2Cl– in aqueous solution at T = 25°C and I = 0.2 M (NaCl), log β1 = 9.22, log β2 = 16.61 have been studied. For bipyridyl complexes Au(bipy)(X = Cl, OH) at pH 2.0 and 7.4, redox interactions with anions of thiol-containing acids (glutathione, cysteine, thiomalate) have been studied. In all cases, at the initial stage, a rapid reduction of gold(III) to gold(I) was observed with the simultaneous release of bipyridyl. A detailed analysis of UV spectra showed that the main products of gold(III) reduction are highly stable gold(I) thiolate complexes. The presence of further slower steps depends on the initial ratio of thiol to gold.
