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 compare
