Descripción

General description

Gold(I) chloride is a yellow crystalline solid with a monoclinic structure. It sublimes at elevated temperatures. Gold(III)chloride is thermally decomposed to produce gold(I) chloride. It is widely used as a precursor to prepare gold nanoparticles and catalyst systems.

Application

Gold(I) chloride can be used:

• As a precursor to prepare magnetic nanocatalyst systems for various organic transformations. For example, Fe₃O₄@SiO₂-P–AuCl can be used as a catalyst for one-pot reductive amination of aldehydes and ketones with various aromatic amines.
• As a starting material to synthesize Au-containing complexes for application in the field of drug delivery, solar cells, sensors, and organic synthesis.
• As a precatalyst for stereoselective cycloisomerization of α-thioallenes to 2,5-dihydrothiophenes via C-S bond formation.
• As a catalyst for the conversion of siloxy cyclohexadienes, to the corresponding1,2- and 1,3-cyclohexenones via Gold-Catalyzed Cycloisomerization.
