Tetrafenilborato de sodio

Descripción:

Tetrafenilborato de sodio, con el número CAS 143-66-8, es un compuesto organoboro caracterizado por su anión tetrafenilborato emparejado con cationes de sodio. Aparece como un sólido cristalino blanco a amarillo pálido y es conocido por su baja solubilidad en agua, lo que lo hace más soluble en disolventes orgánicos como el benceno y el tolueno. Este compuesto se utiliza a menudo en química analítica, particularmente en la precipitación de ciertos cationes, incluidos los metales alcalinos y los metales de transición, debido a su capacidad para formar sales insolubles. Tetrafenilborato de sodio también se emplea en la síntesis de varios compuestos organometálicos y como reactivo en la síntesis orgánica. Su estructura presenta un átomo de boro unido a cuatro grupos fenilo, lo que contribuye a sus propiedades únicas, incluida la estabilidad y la capacidad de actuar como un anión no coordinante. Se deben observar precauciones de seguridad al manipular este compuesto, ya que puede representar riesgos para la salud si se ingiere o inhala, y se debe utilizar el equipo de protección adecuado.

Sodium tetraphenylborate

CAS: 143-66-8

Sodium tetraphenylborate is a chemical compound that is a salt of tetraphenylborate. It is used in the laboratory for the preparation of stable complexes with nitrogen atoms, including reaction solutions and light exposure. Sodium tetraphenylborate has been shown to be an effective catalyst for the Suzuki coupling reaction. The intracellular calcium concentration increases as a result of this reaction and this increase can be measured using titration calorimetry. This reaction also produces ester linkages in addition to hydroxyl groups, which are present due to the presence of a carboxylic acid group on one or more of the reactants.
