been able to furnish information about the effects of the nature of the 3-acyl structure and of the 5-substituents in the 1,2,4-oxadiazole ring on the reactivity of the examined rearrangements: they are well in line with the previsions carried out considering some our previous computational results as well as experimental kinetic ones.
3-酰基-
1,2,4-恶二唑3a – c的Z-苯基hydr单核重排为相关的2-苯基-2 H -
1,2,3-三唑类(4a – c)已在不同温度下在较大的质子浓度范围内的
二恶烷/
水中进行了测量。已经观察到两种不同反应途径的发生(一种是未催化的,
水辅助的,另一种是一般的碱催化的)。获得的结果已经能够提供有关
1,2,4-恶二唑环中3-酰基结构和5-取代基的性质对所检查的重排反应性的影响的信息:它们很一致考虑到我们先前的一些计算结果以及实验动力学的结果,进行了预想。
