CAS 1291-32-3: Bis(ciclopentadienil)zirconio dicloruro
Descripción:
Bis(ciclopentadienil)zirconio dicloruro, comúnmente conocido como Cp2ZrCl2, es un compuesto de coordinación que presenta un centro de zirconio coordinado a dos ligandos ciclopentadienilo (Cp) y dos iones cloruro. Este compuesto se caracteriza por su distintiva estructura de sándwich, donde el átomo de zirconio se sitúa entre los dos anillos de Cp, que son conocidos por su capacidad para estabilizar centros metálicos. Típicamente aparece como un sólido y es soluble en disolventes orgánicos. La presencia de los grupos dicloruro contribuye a su reactividad, lo que lo convierte en un precursor útil en varias reacciones químicas, particularmente en la química organometálica y la catálisis. Cp2ZrCl2 se emplea a menudo en procesos de polimerización, especialmente en la producción de poliolefinas, debido a su capacidad para activar olefinas. Además, exhibe propiedades electrónicas interesantes, que pueden verse influenciadas por la naturaleza de los sustituyentes en los anillos ciclopentadienilos. En general, este compuesto es significativo tanto en la investigación académica como en aplicaciones industriales, mostrando la versatilidad de los complejos de metales de transición.

CAS: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.

CAS:Zirconocene dichloride is a zirconium compound that reacts with ethylene diamine to produce the active species, zirconocene. Zirconocene then reacts with activated sodium salts in the presence of water vapor to form the corresponding zirconium oxide. This process is reversible and has been shown to be a single-step reaction that produces high yields of zirconium oxide. The deuterium isotope effect has been observed in this process, which is due to the incorporation of deuterium into the product.Fórmula:C10H10Cl2ZrPureza:Min. 95%Peso molecular:292.32 g/mol
