(+)-BINOL

Descrizione:

(+)-BINOL, o 1,1'-bi-2-naftolo, è un composto organico chirale caratterizzato dai suoi due anelli di naftalene collegati da un legame singolo con gruppi idrossilici nelle posizioni 1 e 1'. È un solido incolore a giallo pallido che è scarsamente solubile in acqua ma solubile in solventi organici come etanolo ed etere. Il composto mostra una forte attività ottica a causa della sua natura chirale, rendendolo un importante mattone nella sintesi asimmetrica e un ligando chiave in vari processi catalitici. (+)-BINOL può partecipare a legami idrogeno grazie ai suoi gruppi idrossilici, influenzando la sua reattività e interazioni con altre molecole. È ampiamente utilizzato nella sintesi di catalizzatori chirali e nello sviluppo di reazioni enantioselettive, in particolare nel campo della chimica organica. Inoltre, i suoi derivati possono servire come precursori per composti organici più complessi, dimostrando la sua versatilità nelle applicazioni sintetiche.
