Özet

In the present article our research work is focused on the synthesis of coumarin, triazole drieved Schiff bases as well as to synthesize the variety of metal complexes with various transition metal ions. Starting from the synthesis of 4-amino-2-[(5-amino-1,3,4-oxadiazol-2-yl)methyl]-5-(2-furoyl)-2,4-dihydro-3H-1,2,4-triazol-3-one (2) which was performed by using 2-[4-amino-3-(2-furoyl)-5-oxo-4,5-dihydro-1H -1,2,4-triazol-1-yl] acetohydrazide (1) as starting metarial. The treatment of (2) with divers coumarin aldehydes (5, 9, 12, 15 and 19) afforded the corresponding Schiff bases (6, 10, 1 3, 16, and 20). Newly synthesized N'-[(1Z)-(7,8-dimethoxy-2-oxo-2H-chromen-4-yl)methylene]-4-{[(1Z)-(7,8-dimethoxy-2-oxo-2H-chromen-3-yl)methylene]amino }-3-(2-furoyl) -5-oxo -4,5 -dihydro-1H-1,2,4-triazole-1-carbohydrazide derivatives, have been characterized by spectroscopic measurements (IR, H-1-NMR, C-13-NMR).
