ÖZET BAZI 4-ARİLİDENAMİNO-4.5-DİHİDRO-1,2,4-TRİAZOL-5-ON'LARIN SENTEZİ ve ÖZELLİKLERİNİN İNCELENMESİ Bu çalışmada, bazı 3-alkü(arü)^-amino-4,5-dihidro-l,2,4-triazol-5-on'lann furan- 2-karboksialdehid (furfural) ve tiyofen-2-karboksialdehid ile reaksiyonlan incelenmiş, 14 yeni 3-alkü(arü)^-(2-fürMelilenamino)-4,5-dihidro-l,2,4-triazol-5-on ve 3-alkil (aril)-4-(2-tiyenilmetilenamino)-4,5-dihidro-l,2,4-triazol-5-on bileşikleri sentez edil miştir. Çalışmada elde edilen yeni bileşiklerin yapı aydınlatmaları için mikroanaliz, İR, *H NMR ve UV spektroskopisi yöntemleri kullanılmıştır. Anahtar Kelimeler: 3-alkil(aril)-4-amino-4,5-dihidro-l,2,4-triazol-5-on, füran-2- karboksialdehid, tiyofen-2-karboksialdehid.

SUMMARY THE SYNTHESIS OF SOME 4-ARYLH)ENAMINO-4,5-DmYDRO-l,2,4- TRIAZOL-5-ONES AND INVESTIGATION OF THEIR PROPERTIES In this study, the reactions of some 3-alkyl(aryl)^amino-4,5-dihydro-l,2,4-triazol- 5-ones with furan-2-carboxyaldehyde (furfural) and thiophene-2-carboxy-aldehyde were investigated and 14 new 3-alkyl(aryl)^(2-furylmethyleneamino)-4,5-dihydro- 1,2,4-triazol-5-ones and 3-alkyl(aryl)^-(2-tWenylmethyleneamino)-4,5-di-hydro- 1,2,4- triazol-5-ones were synthesized. In order to identify the new compounds synthesized in the study, combustion analyses and spectroscopic methods including IR, XH NMR and UV were used. Keywords: 3-alkyl(aryl)-4-amino-4,5-dihydro-l,2,4-triazol-5-one, furan-2-carboxy- aldehyde, thiophene-2-carboxyaldehyde. VI
