Derivatives of 2,3-dihydro-1H-1,5-benzodiazepine were obtained by the reaction of 4-chloro-, 4-bromo- 3,5-dichloro-, and 4-cyano-substituted ortho-phenyl-enediamines with 4-R-acetophenones in the presence of concentrated sulfuric acid. Electron-withdrawing groups R increase the reaction rate and consequently promote the formation of a mixture of isomeric products. The structure of the compounds and the composition of their mixtures were established by PMR spectroscopy. The reaction mechanism is discussed.
