(-)-Binol

Descrizione:

(-)-Binol, noto anche come 1,1'-bi-2-naftolo, è un composto organico chirale caratterizzato dai suoi due anelli naftalenici collegati da un legame singolo, con gruppi idrossilici (-OH) posizionati nelle posizioni 1 e 1'. Questo composto è notevole per la sua capacità di agire come ligando chirale nella sintesi asimmetrica, rendendolo prezioso in varie reazioni chimiche, in particolare nella catalisi. (-)-Binol mostra una forte attività ottica grazie alla sua natura chirale, permettendogli di ruotare la luce polarizzata nel piano. È tipicamente un solido cristallino bianco a bianco sporco ed è solubile in solventi organici come etanolo e acetone, ma meno solubile in acqua. La stereochimica del composto gioca un ruolo cruciale nella sua reattività e interazioni, rendendolo un attore chiave nello sviluppo di processi enantioselettivi in chimica organica. Inoltre, (-)-Binol può subire varie trasformazioni, inclusa l'ossidazione e l'esterificazione, ampliando ulteriormente la sua utilità nelle applicazioni sintetiche.

(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.
