Using 5-methoxy-2-aryl-1,3,4-oxadiazoles as models it was shown that the thermal rearrangement of imino-ethers to N-alkylamides proceeds through a double ionic mechanism; kinetic measurements in the solid state and in the melt give apparent activation energies that support ab initio calculated activation enthalpies.
以 5-甲氧基-2-芳基-1,3,4-恶二唑为模型,研究表明亚
氨基醚到 N-烷基酰胺的热重排是通过双离子机制进行的;在固态和熔体中进行的动力学测量给出了表观活化能,支持 ab initio 计算的活化焓。
