(+)-BINOL

Descrição:

(+)-BINOL, ou 1,1'-bi-2-naftol, é um composto orgânico quiral caracterizado por seus dois anéis de naftaleno conectados por uma ligação simples com grupos hidroxila nas posições 1 e 1'. É um sólido incolorido a amarelo pálido que é pouco solúvel em água, mas solúvel em solventes orgânicos como etanol e éter. O composto exibe forte atividade óptica devido à sua natureza quiral, tornando-se um bloco de construção importante na síntese assimétrica e um ligante chave em vários processos catalíticos. (+)-BINOL pode participar de ligações de hidrogênio devido aos seus grupos hidroxila, influenciando sua reatividade e interações com outras moléculas. É amplamente utilizado na síntese de catalisadores quirais e no desenvolvimento de reações enantiosseletivas, particularmente no campo da química orgânica. Além disso, seus derivados podem servir como precursores para compostos orgânicos mais complexos, demonstrando sua versatilidade em aplicações sintéticas.
