CAS 136040-19-2: Tetrakis(pentafluorofenil)borato de trifenilcarbenio
Descripción:
Tetrakis(pentafluorofenil)borato de trifenilcarbenio es una especie catiónica estable y altamente reactiva caracterizada por su núcleo de triphenilcarbenio, que es un átomo de carbono trivalente unido a tres grupos fenilo. Este compuesto es notable por su fuerte naturaleza electrofílica debido a la carga positiva en el átomo de carbono, lo que lo convierte en un potente ácido de Lewis. El anión tetrakis(pentafluorofenil)borato actúa como un contraión, proporcionando una estabilización significativa al catión a través de la resonancia y los efectos de atracción electrónica de los grupos pentafluorofenilo. La presencia de múltiples átomos de flúor aumenta la deficiencia electrónica del borato, aumentando aún más la estabilidad de la estructura en general. Este compuesto se utiliza a menudo en síntesis orgánica y catálisis, particularmente en reacciones que involucran sustitución aromática electrofílica y como reactivo en varias transformaciones químicas. Sus propiedades únicas lo convierten en una herramienta valiosa en el estudio de la química de carbocationes y el desarrollo de nuevas metodologías sintéticas.

CAS:Trityl tetrakis(pentafluorophenyl)borate is a reactive metal-organic compound that is used as an efficient and stereoselective method for the synthesis of trifluoromethanesulfonic acid. The Friedel-Crafts reaction involves the reaction of a halogenated aromatic compound with an alkyl or aryl group, which can be activated by a cocatalyst such as zinc chloride. Trityl tetrakis(pentafluorophenyl)borate has been shown to produce trifluoromethanesulfonic acid in high yields when reacted with zirconium dichloride and a cocatalyst of triethylsilane. This method can be used to synthesize various disaccharides, including maltose, cellobiose, and sucrose.Fórmula:C43H15BF20Pureza:Min. 95%Peso molecular:922.36 g/molTriphenylmethylium tetrakis(perfluorophenyl)borate
