| Application: | 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 • 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-dihydronaph |
