dc.description.abstract | 1,2,4-OKSADIAZOL ve 1,2,4-TIYADIAZOL TÜREVLERİNİN SENTEZİ KAZIM KAHRAMAN Anahtar Kelimeler: Tiyolama, çevrilme, ince tabaka kromatografisi(T.L.C.),infrared spektroskopisi (İR), kütle spektroskopisi (KÜTLE), nüklüer magnetik rezonans spektroskopisi (NMR). Özet: N-Substitue amidoksimlerin etil kloroformat ile reaksiyonundan 3,4- disubstitue -1,2,4- oksadiazol-5(4H)-on bileşikleri elde edildi. Bu bileşiklerin P2Ss ile tiyolanması, karşılık gelen 1,2,4- oksadiazol -5- tiyon bileşiklerini verdi. 1,2,4- Oksadiazol-5-tiyon bileşiklerinin katalitik miktarda bakır katalizörü ile birlikte termal çevrilmesinden l,2,4-tiyadiazol-5-on bileşikleri elde edildi. Bu bileşiklerinin P2Ss ile reaksiyonundan ise l,2,4-tiyadiazol-5-tiyon bileşikleri ele geçti. | |
dc.description.abstract | SYNTHESİS OF 1,2,4-OXADIAZOLE and 1,2,4-THIADIAZOLE DERIVATIVES KAZIM KAHRAMAN Keyworrds: Thionation, thione-thiol rearrangement, thin layer chromatography (T.L.C.), infrared spectroscopy (IR), mass spectroscopy (MS), nuclear magnetic resonance spectroscopy (N.M.R). Abstract: 3,4-Disubstituted-l,2,4-oxadiazole-5(4H)-ones were obtained from the reaction of N-substituted amide oximes with ethylchloroformate. These compounds were treated with P2S5 to give corresponding l,2,4-oxadiazole-5-thiones. Rearrangement of 1,2,4 -oxadiazole-5-thiones, catalysed by metallic copper, yielded l,2,4-thiadiazole-5-ones. The reaction of l,2,4-thiadiazole-5-ones with P2S5 gave 1,2,4-thiadiazole-5-thiones. | en_US |
