(-)-Binol

Descripción:

(-)-Binol, también conocido como 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 (-OH) posicionados en las posiciones 1 y 1'. Este compuesto es notable por su capacidad para actuar como un ligando quiral en la síntesis asimétrica, lo que lo hace valioso en varias reacciones químicas, particularmente en catálisis. (-)-Binol exhibe una fuerte actividad óptica debido a su naturaleza quiral, lo que le permite rotar la luz polarizada en plano. Típicamente es un sólido cristalino blanco a blanco sucio y es soluble en disolventes orgánicos como etanol y acetona, pero menos soluble en agua. La estereoquímica del compuesto juega un papel crucial en su reactividad e interacciones, convirtiéndolo en un actor clave en el desarrollo de procesos enantioselectivos en química orgánica. Además, (-)-Binol puede sufrir varias transformaciones, incluida la oxidación y la esterificación, ampliando aún más su utilidad en aplicaciones sintéticas.

(S)-1,1'-Bi-2-Naphthol

CAS: 18531-99-2

The chemical structure of 1,1'-bi-2-naphthol is an alkanoic acid with a hydroxyl group. It has been shown to react in the presence of amines and sodium salts to form hydrogen bonding interactions. The x-ray crystal structures of magnesium salt and hydrogen bonding interactions were found to have a steric interaction with the fatty acids. The reaction mechanism for 1,1'-bi-2-naphthol is similar to that of other alkanoic acids: it reacts with a nucleophilic compound, such as water or ammonia, to produce an alcohol (hydroxyl group). When these reactions occur intramolecularly, the hydrogen bonds are formed between adjacent molecules.
