Abstract
- Bu çalışmada potansiyel herbisit olarak yeni 1,2,4-triazin ve pirazin-2,3-dikarbonitril iskeletine sahip heterosiklik bileşikler sentezlenmiştir. Metot başlangıç maddesi olan bazı furan-2,3-dionların, S-metilizotiyosemikarbazit ve diaminomaleonitril ile yeniden halkalaşma reaksiyonuna dayanır. Buna ilave olarak sentezlenen pirazin-2,3-dikarbonitril bileşiklerinin hidrolizi edilerek bu bileşiklerin bazı türevleri elde edilmiştir.Sentezlenen yeni bileşikler moleküler spektroskopik metotlarla karakterize edilmiştir. In this study, novel 1,2,4-triazine and pyrazine-2,3-dicarbonitrile derivatives were synthesized as potential herbicides. The method was based on cyclocondensation of furan-2,3-diones with S-methylisothiosemicarbazide and diaminomaleonitrile. Moreover, the synthesized pyrazine-2,3-dicarbonitrile derivatives were transformed to its corresponding new derivatives by hydrolyze reactions.The synthesized new compounds were characterized with molecular spectroscopic methods. 80
