Several hitherto unknown 3,5,7-triaryl-5,6-dihydro-4H-1,2,5-triazepines have been synthesised by cyclocondensation of N,N-bis(phenacyl)anilines with hydrazine hydrate in ethanol or ethyleneglycol under reflux condition. Increased yields were obtained in the presence of p-toluenesulfonic acid compared to the uncatalysed reaction.
在乙醇或乙二醇中,在乙醇或乙二醇中,N,N-双(苯甲酰基)苯胺与水合肼的环缩合反应合成了几种迄今未知的3,5,7-三芳基-5,6-二氢-4 H -1,2,5-三氮杂ze回流条件。与未催化的反应相比,在对甲苯磺酸的存在下获得增加的产率。
