The regioselectivity of the fluorination of various allylic and β-dienoic alcohols with DAST has been studied. Substituent effects are important in these reactions; a strong preference for the secondary fluorides versus the primary ones is observed, especially in the case of alkyl and aryl substituted derivatives.
研究了用DAST氟化各种烯丙基和β-二烯醇的区域选择性。在这些反应中,取代基的作用很重要。观察到仲氟化物相对于伯氟化物的强烈偏爱,特别是在烷基和芳基取代的衍生物的情况下。
