Abstract A convenient, one pot procedure is reported for the synthesis of a variety of 2,5-disubstituted-1,3,4-oxadiazoles by condensing mono-arylhydrazides with acid chlorides in HMPA solvent under the microwave heating. The yields are good to excellent, the process is rapid and does not need any added acid catalyst or dehydrating reagent.
摘要 报道了一种方便的单锅法,通过在 HMPA 溶剂中在微波加热下将单芳基酰肼与酰氯缩合来合成各种 2,5-二取代-1,3,4-恶二唑。收率从好到极好,过程快速,无需添加任何酸催化剂或脱水剂。
