of three novel ligands, in which an azaheterocycle is connected with a thiazole subunit: 4-methoxy-5-methyl-2-pyridine-2-yl-1,3-thiazole (1), 4-methoxy-5-methyl-2-pyrimidine-2-yl-1,3-thiazole (2) and 4-methoxy-5-phenyl-2-pyridine-2-yl-1,3-thiazole (3) are reported. Because these ligands are cyclic versions of 1,4-diazadienes, they offer good prerequisites for the synthesis of metal complexes and were
在此合成了三个新型配体,其中氮杂杂环与噻唑亚基相连:4-甲氧基-5-甲基-2-吡啶-2-基-1,3-噻唑 (1), 4-甲氧基-5-报道了甲基-2-嘧啶-2-基-1,3-噻唑 (2) 和 4-甲氧基-5-苯基-2-吡啶-2-基-1,3-噻唑 (3)。由于这些配体是 1,4-二氮杂二烯的环状形式,它们为金属配合物的合成提供了良好的先决条件,并被用作螯合配体。成功合成了三种新型的 Ru(bpy)2(L) 型杂配阳离子配合物,bpy = 2,2'-联吡啶。RuII配合物以及配体通过质谱、NMR、UV/Vis和IR光谱以及元素分析来表征。此外,Ru(bpy)22(PF6)的X射线结构,
