Microwave‐enhanced highly efficient protocol for the synthesis of polyfunctional pyridazines beginning from 3,6‐dichloropyridazine in environmentally benign ionic liquids have been developed. The products obtained were 3‐amino‐6‐chloropyridazine, 3,6‐diaminopyridazine, and 3‐chloro‐6‐methoxypyridazine. These derivatives were then be converted to a variety of polyfunctional pyridazine derivatives. The ionic liquids
已开发出微波增强的高效方案,用于在环境无害的离子液体中合成从3,6-二氯哒嗪开始的多官能哒嗪。得到的产物是3-氨基-6-氯哒嗪,3,6-二氨基哒嗪和3-氯-6-甲氧基哒嗪。然后将这些衍生物转化为多种多官能哒嗪衍生物。所使用的离子液体为1 - n-丁基-3-甲基咪唑鎓氢氧化物/四氟硼酸酯/六氟磷酸盐和1,3-二-n-丁基咪唑鎓氢氧化物。这种强大的策略是耗时少的绿色方法。所使用的离子液体可以回收和再循环。
