This is the first report on the PEG-300-mediated one-pot synthesis of 2-(2-hydrazinyl) thiazole derivatives from ketones, thiosemicarbazide, and α-halo ketones. Here PEG-300 acts as a solvent as well as supporting catalyst. Formation of compounds was confirmed by IR, 1H NMR, 13C NMR, and mass spectroscopic studies. A series of 2-(2-hydrazinyl) Thiazole derivatives have been synthesized from substituted
摘要 噻唑是重要的含硫分子,广泛应用于制药、农用化学品和材料科学等多个领域。这是关于 PEG-300 介导的从酮、氨基硫脲和 α-卤代酮一锅合成 2-(2-肼基) 噻唑衍生物的报告。在这里 PEG-300 作为溶剂和负载催化剂。通过IR、1H NMR、13C NMR和质谱研究证实了化合物的形成。使用 PEG-300 作为反应介质,通过一锅法从取代酮、氨基硫脲和 α-卤代酮合成了一系列 2-(2-肼基) 噻唑衍生物。图形概要
