摘要 我们报告了一种新型的合成咪唑并[1,5 - a ]吡啶-1-羧酸的有效方法。通过使2-(氨基甲基)吡啶与酰氯反应,然后用三氟乙酸酐一锅处理,得到2,2,2-三氟-1-咪唑并[1,5 - a ]吡啶-1-丙酮酮,然后通过卤代形式裂解以高制备产率将其转化为咪唑并[1,5 - a ]吡啶-1-羧酸。 我们报告了一种新型的合成咪唑并[1,5 - a ]吡啶-1-羧酸的有效方法。通过使2-(氨基甲基)吡啶与酰氯反应,然后用三氟乙酸酐一锅处理,得到2,2,2-三氟-1-咪唑并[1,5 - a ]吡啶-1-丙酮酮,然后通过卤代形式裂解以高制备产率将其转化为咪唑并[1,5 - a ]吡啶-1-羧酸。

We find a Cu(II)-(L-CF3)2 complex (L-CF3 = 2,2,2-trifluoro-N-[2-(pyridin-2-yl)propan-2-yl]acetamide) with a distorted “seesaw” geometry. It has the shortest crystallographic CF···Cu distances yet reported, to the best of our knowledge (<2.6 Å), for which computational and experimental data indicate a secondary bonding interaction. A comparison with a CCl3 version and one without ligand backbone gem-dimethyl

A practical and efficient cleavage of trifluoroacetamides with p-TsOH·H2O has been developed. The deprotected amines are isolated directly from the reaction mixture as tosylate salts. This method can be applied to both secondary and tertiary trifluoroacetamides in good isolated yields.

and pyridyl amides to act as cooperating ligands in the C−H activation of arenes has been tested by independent experiments. Isolated complexes [Pd(κ2-ligand)(C6F5)py]x− (x=1, 0; ligand=6-oxidopicolinate, pyridyl-amide) were decomposed in arenes leading to the C−H activation of the latter and C6F5-arene coupling products in different amounts which allows to rank the ability of both ligands.
6-羟基吡啶甲酸和吡啶酰胺在芳烃的 C−H 活化中作为协同配体的能力已通过独立实验进行了测试。分离的复合物 [Pd(κ 2 -配体)(C 6 F 5 )py] x− (x=1, 0;配体=6-氧化吡啶甲酸酯,吡啶基酰胺)在芳烃中分解,导致后者的 C−H 活化和不同量的 C 6 F 5 -芳烃偶联产物,这使得对两个配体的能力进行排名。
