of these three new derivative ligands to the copper(II) ion resulted in the formation of three new complexes: dichlorobis(N-(2H-[1,2,4]thiadiazolo[2,3-a]pyridine-2-ylidene)benzamide)copper(II), dichlorobis(N-(7-methyl-2H-[1,2,4]thiadiazolo[2,3-a]pyridine-2ylidene)benzamide)copper(II), and dichlorobis(N-(5-methyl-2H-[1,2,4]thiadiazolo[2,3-a]pyridine-2-ylidene)benzamide)copper(II).

通过一锅中硫氰酸钾,苯甲酰氯和2-氨基吡啶衍生物的反应,合成了三种N-(吡啶-2-基氨基甲硫基)苯甲酰胺衍生物。使用氯化铜(II)将获得的衍生物氧化。在氧化过程中,两个氢原子被除去,衍生物发生环化,最后,三个新的N-(2 H- [1,2,4]噻二唑并[2,3 - a ]吡啶-2-亚甲基)苯甲酰胺衍生物被生产了。这三个新的衍生物配体与铜(II)离子的配位导致形成了三个新的配合物:二氯双(N-(2 H- [1,2,4]噻二唑并[2,3- a]吡啶2ylidene)苯甲酰胺)铜(II),二氯双(ñ - (7-甲基-2 ħ - [1,2,4]噻二唑并[2,3-一个]吡啶2ylidene)苯甲酰胺)铜(II)和二氯双(N-(5-甲基-2 H- [1,2,4]噻二唑并[2,3 - a ]吡啶-2-亚甲基)苯甲酰胺)铜(II)。通过IR,1 H NMR和13 C NMR光谱对所有合成产物进行表征。所获得
