Polyethylene glycol (PEG) was found to be an inexpensive nontoxic and effective medium for the synthesis of imidazo[2,1-b]-1,3,4-thiadiazoles in the presence of potassium carbonate as a green base in high yields. In addition, the solvent system can be recovered and reused, making this protocol economically and potentially viable.
聚乙二醇(PEG)被发现是一种廉价的无毒,有效的介质,可在存在下列条件下合成咪唑并[2,1 - b ] -1,3,4-噻二唑。碳酸钾为绿色碱,高产。另外,溶剂系统可以回收和再利用,从而使该方案在经济上和潜在可行。
