Digging for gold: Mixtures of tetraethylthiuram disulfide (Et4TDS) and I2 in acetone are capable of dissolving elemental gold and forming valuable metal complexes, in which the stoichiometry depends on the mixture composition. These mixtures can also etch the gold layer homogeneously and selectively from Si/SiO2/Ti/Au thin‐layered structures under mild conditions (see figure).
