dc.description.abstractÖZET On altısı literatürde bilinen 67' si orijinal olan toplam 83 bileşiğin sentezlendiği bu çalışmada önce bazı açilhidrazon'lar sentezlenmiş ve bu bileşikler bidrazin hidrat ile muamele edilmek suretiyle 4-amino-4H-l,2,4-triazoPlere dönüştürülmüştür. Açilhidrazon'larm sentezi sırasında 1,3,4-oksadiazol'ler de ele geçmiştir. Elde edilen 4- arnino-4H-l,2,4-triazoPler değişik aldehit ve ketonlarla reaksiyona sokularak kendilerine karşılık gelen 3,5-dialkil-4-(benzilidenamino)-4H-l,2,4-triazol'ler elde edilmiştir. 3,5-dialkil-4-alkilamino-4H- 1,2,4-triazor lerin sentezi ise elde edilen schiff bazlarının azometin grubunun indirgenmesi yoluyla gerçekleştirilmiştir. Elde edilen 4-amino-4H- 1,2,4-triazol'ler asetik anbidrid ile muamele edilerek 138, 140, 141 no'lu 4-amino bileşikleri N-asetil türevlerine; 134 ve 139 bileşikleri ise Oasetil türevlerine dönüştürülmüştür. Çalışmada elde edilen 67 yeni bileşiğin yapılan İR, lH-NMR, `C-NMR ve UV spektroskopisi yöntemleri kullanılarak aydınlatılmış, çalışmada uygulanan reaksiyonlar için reaksiyon mekanizmaları önerilmiştir. Anahtar Kelimeler: Acil hidrazon'lar, İminoester hidroklorür'ler, 1,2,4- Triazol'ler, 1,3,4-Oksadiazol'ler, Schiff bazları, Azometin grubu, Aldehitler, Ketonlar, İndirgenme, NaBH4, Nükleofilik katılma, Açillendirme.

dc.description.abstractSUMMARY Synthesis of Some Ester Acylhydrazones and 4-aIkylamino-3,5-dialkyl-4H-l,2,4~ triazoles by Cyclisation and Reduction of Ester Acylhydrazones In this study, initially, some acylhydrazones were synthesized and subsequently, by the reaction of these compounds with hydrazine hydrate 3,5-dklkyl-4-amino-4H-l,2,4- triazoles were obtained. While preparing acylhydrazones, 1,3,4-oxadiazoles were also obtained. 3,5-dialkyl-4-benzyUdenammo-4H-l,2,4-triazoles were synthesized by the reaction of 4-arnino-4H-l,2,4-triazoles with various aromatic aldehydes and ketones. Some selected compounds with Schiff base character were converted to their acetyl derivatives by treating with acetic anhydride. The synthesis of some 3,5-dialkyl^alkylamino-4H-l,2,4-triazoles were followed by the reduction of azomethine groups of the bases obtained with NaBR*. The structures of 67 new compounds synthesized in this study were proposed by evaluating the data obtained using spectroscopic methods such as IR, ^-NMR, 13C-NMR Some physical properties of these compounds were determined and their UV spectra were recorded. Moreover, reaction mechanisms were proposed for the general reactions. KeyWords: Acyl hydrazones, Iminoester hydrochlorides, 1,2,4-Triazoles, 1,3,4- Oxadiazoles, Schiff bases, Azomethyne group, Aldehydes, Ketones, Reduction, Nucleophilic addition, Acylation. VIIIen_US
