Gold complexes of L-cysteine and D-penicillamine
Abstract
The preparation of a range of gold-(I) and -(III) complexes of L-cysteine and D-peniciltamine is described. In the presence of chloride, L-cysteine forms gold(I) complexes and D-penicillamine forms gold(III) complexes. In the presence of triphenylphosphine only gold(I) complexes are obtained. Ultraviolet–visible spectra are reported.
