is described. Numerous 3-aryl-1,3,4-oxadiazolium salts, containing a novel type of heterocyclic cation, have been prepared by the action of carboxylic anhydrides on diacylarylhydrazines in the presence of perchloric or fluoroboric acid. 1,3,4-Oxadiazolo[3,2-a]pyridinium salts are similarly formed from 1 -acylamino-2-pyridones. The stability of the salts and their i.r. and n.m.r. spectra are discussed
已经研究了一些简单的1,3,4-恶二唑的质子化和烷基化,并描述了一种新的1,3,4-恶二唑的合成。在高氯酸或氟硼酸的存在下,通过羧酸酐对二酰基芳基肼的作用,已经制备了许多含有新型杂环阳离子的3-芳基-1,3,4-恶二唑鎓盐。类似地由1-酰基氨基-2-吡啶酮形成1,3,4-氧杂二唑[3,2- a ]吡啶鎓盐。讨论了盐的稳定性及其ir和nmr光谱。
