애플리케이션

Gold(III) chloride trihydrate can be used as a gold precursor salt for the production of gold nanoparticles (AuNP) using various reducing agents.
It can also be used as a catalyst in the following processes:
  • HAuCl4 3H2O inPEG 400 is used to synthesize spirochromene derivatives via a one-pot three-component reaction of isatins/acenaphthoquinone, active methylene compounds, and cyclic 1,3-diketones/4-hydroxycoumarin.      
  • Au/CeO2 catalytic system is used in chemoselective oxidation of aromatic/aliphatic alcohols to corresponding carbonyl compounds.      
  • Used in the synthesis of allylnaphthalenes by ring-opening of 1,4-epoxy-1,4-dihydronaphthalenes with allyltrimethylsilane.
