3-diols, selective mono-benzoylation occurs to afford mono-esters of the diols in good yield. The reaction is completed under mild conditions in a short reaction time. Further, prim-, sec-, and tert-diols and catechol can be converted to the corresponding mono-benzoates. DFBA is used for the protection of the hydroxy group in sugars. The selective mono-nicotinylation, formylation and pivaloylation of diols
在N,N-二乙基-α,α-二氟苄胺(DFBA)与1,2-或1,3-二醇的反应中,发生选择性的单苯甲酰化以良好的产率提供二醇的单酯。反应在温和的条件下在短时间内完成。此外,整洁- ,仲- ,和叔-diols和儿茶酚可以转化为相应的单苯甲酸酯。DFBA用于保护糖中的羟基。还通过使用相应的二氟烷基胺来进行二醇的选择性单-烟酰胺基化,甲酰化和聚乙烯醇缩合。
