(+)-BINOL

Descripción:

(+)-BINOL, o 1,1'-bi-2-naftol, es un compuesto orgánico quiral caracterizado por sus dos anillos de naftaleno conectados por un enlace simple con grupos hidroxilo en las posiciones 1 y 1'. Es un sólido incoloro a amarillo pálido que es poco soluble en agua pero soluble en disolventes orgánicos como el etanol y el éter. El compuesto exhibe una fuerte actividad óptica debido a su naturaleza quiral, lo que lo convierte en un bloque de construcción importante en la síntesis asimétrica y un ligando clave en varios procesos catalíticos. (+)-BINOL puede participar en enlaces de hidrógeno debido a sus grupos hidroxilo, influyendo en su reactividad e interacciones con otras moléculas. Se utiliza ampliamente en la síntesis de catalizadores quirales y en el desarrollo de reacciones enantioselectivas, particularmente en el campo de la química orgánica. Además, sus derivados pueden servir como precursores para compuestos orgánicos más complejos, mostrando su versatilidad en aplicaciones sintéticas.
