“…The thiolato gold(I) complexes [Au(SR)(PRЈ 3 )] (SR = various thiolato derivatives as shown in Scheme 1; PRЈ 3 = PTA, DAPTA) were easily prepared in good yields by treating the complexes [AuCl(PRЈ 3 )] with the thiol derivatives in the presence of base (Scheme 1). The complexes [AuCl-(PTA)] [6] and [AuCl(DAPTA)] were prepared by replacement of tetrahydrothiophene (tht) from [AuCl(tht)] with the appropriate phosphane.…”

“…[1,2] Gold thiolato complexes dispersed in different solvents, including natural resins, have been used as a gold source for decorating ceramic tiles and glasses after heating. [3] Because these dispersions are liquid, they are commonly referred to as "liquid gold" and, when other late transition metals are involved, the name "liquid precious metal" is used. To avoid the use of toxic and volatile solvents, there is an increasing interest in the development of water-soluble "liquid metals" and thus for water-soluble thiolato complexes.…”

“…The use of such reactions for the preparation of thioether and disulfide molecules is known in organic chemistry [7]. However the same chemical process has only occasionally been exploited to produce the inorganic phase (e.g., noble-metal coatings on ceramic substrates [8]). In the present work, the controlled thermolysis of alkane-thiolates dissolved in amorphous polystyrene has been used to generate polymer-embedded metals or metal sulfides of nanoscopic size.…”

Transition-metal alkane-thiolates (i.e., organic salts with formula Me(SR) x , where R is a linear aliphatic hydrocarbon group, -C n H 2n+1 ) undergo a thermolysis reaction at moderately low temperatures (close to 200 °C), which produces metal atoms or metal sulfide species and an organic by-product, disulfide (RSSR) or thioether (RSR) molecules, respectively. Alkane-thiolates are non-polar chemical compounds that dissolve in most techno-polymers and the resulting solid solutions can be annealed to generate polymer-embedded metal or metal sulfide clusters. Here, the preparation of silver and gold clusters embedded into amorphous polystyrene by thermolysis of a dodecyl-thiolate precursor is described in detail. However, this chemical approach is quite universal and a large variety of polymer-embedded metals or metal sulfides could be similarly prepared.

“…Closing the circle all the way back to the Lycurgus cup the use of MPCs of gold, silver and alloys for decorative purposes is probably the commercially most significant application at the moment [114]. Along with Au(I) mercaptides, MPCs of gold and gold/silver alloys are used as metal paints and inks to decorate glassware, porcelain and similar items [114].…”
