Description and Uses

Bis(cyclopentadienyl)zirconium(IV) Dichloride or zirconocene dichloride is one of numerous organo-metallic compounds (also known as metalorganic, organo-inorganic and metallo-organic compounds) sold by American Elements under the trade name AE Organo-Metallics^TM. As is the case for other transition metal metallocenes, bis(cyclopentadienyl)zirconium(IV) dichloride is most often used as a catalyst.

Bis(cyclopentadienyl)zirconium dichloride is used for for Stereoselective Glycosidation. It is also used in the catalyzed transamidation of primary amides with amines. Zirconocene dichloride can also be used to prepare the Negishi reagent,in oxidative cyclisation reactions. Other applications include it is used to promote greener amidations of carboxylic acids and amines in catalytic amounts. This technology avoids the requirement of preactivation of the carboxylic acid or use of coupling reagents.
