Abstract

The interaction of thiourea (TU) and selenourea (SeU) with aurothiomalate (Autm) has been studied by ^I3C NMR spectroscopy. At a 1:1 ratio of TU:Autm, TU binds to Autm forming a ternary TU-Au-tm complex. However, in the presence of SeU at various mol ratios, some of the thiomalate (Htm) was ejected from Autm as a free ligand, oxidized to tm₂, and gold(I) was reduced to metallic gold. This redox reaction is observed only in the presence of SeU which may be acting as a catalyst.
