(thio)amidoindole moieties were evaluated in the presence of anions as potent anion receptors and/or acidic partners involved in acid–base reactions. In particular, we focused on their behavior at the acid–base half-equivalence point in the presence of basic anions such as fluoride and benzoate salts. Among three isolated X-ray structures, an amidoindole in the presence of fluoride and hexafluorophosphate
在阴离子作为强阴离子受体和/或参与酸碱反应的酸性伙伴的存在下,评估了基于(硫代)酰氨基吲哚部分的氢键催化剂。我们特别关注在碱性阴离子(如氟化物和苯甲酸盐)存在下它们在酸碱半当量点的行为。在三个孤立的 X 射线结构中,在存在氟化物和六氟磷酸盐的情况下,在酸碱半当量点处,形成了一种前所未有的夹心复合物,介于两个受体和一个 PF6- 阴离子之间。
