Résumé

We report here on the synthesis 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). Being cyclic versions of 1,4-diazadienes, they offer good prerequisites for the synthesis of metal complexes and have been employed as chelating ligands. Three novel heteroleptic cationic complexes of the typeRu(bpy)2(L), with bpy = 2,2' bipyridine have been successfully synthesized. The Ru(II) complexes as well as the ligands were characterized by means of mass spectrometry, NMR, UV/Vis and IR spectroscopy and elemental analysis. Furthermore, an X-ray structure of Ru(bpy)22(PF6), as far as we know the first example where a thiazole is directly connected to a Ru(II) core, is presented in this paper.
