Gold Chloride (AuCl3)-Crystalline

Gold Chloride (AuCl3)-Crystalline introduce:

Characteristic




Gold(III) chloride, traditionally called auric chloride, is a chemical compound of gold and chlorine. With the molecular formula Au2Cl6, the name gold trichloride is a simplification, referring to the empirical formula, AuCl3. 




Chemical formula：AuCl3 (exists as Au2Cl6)

Molar mass： 303.325 g/mol

Appearance： Red crystals (anhydrous); golden, yellow crystals (monohydrate)

Density： 4.7 g/cm3

Melting point： 254 °C (489 °F; 527 K) (decomposes)

Solubility in water：68 g/100 ml (cold)

Solubility： soluble in ether, slightly soluble in liquid ammonia

Magnetic susceptibility (χ)：−112·10−6 cm3/mol

Crystal structure：monoclinic




Application




AuCl3 has attracted the interest of organic chemists as a mild acid catalyst for a variety of reactions, although no transformations have been commercialized. 

Some alkynes undergo amination in the presence of gold(III) catalysts. Gold catalyses the alkylation of certain aromatic rings and a conversion of furans to phenols.
