Provided are a heterocyclic carboxylic acid amide ligand and applications thereof in a copper catalyzed coupling reaction. Specifically, provided are uses of a compound represented by formula (I), definitions of radical groups being described in the specifications. The compound represented by formula (I) can be used as the ligand in the copper catalyzed coupling reaction of the aryl halogeno substitute, and is used or catalyzing the coupling reaction for forming the aryl halogeno substitute having C—N, C—O, C—S and other bonds.
The present application is directed to a method for producing non-isocyanate polyurethanes. More particularly, the application is directed to method for producing non-isocyanate polyurethanes by using a single catalyst component selected from an amidoindole derivative, a benzimidazole derivative and a squaramide derivative.
(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。
