Abstract
AbstractHighly substituted, novel, 1,3‐dihydro‐5‐phenyl‐2H‐1,4‐benzodiazepin‐2‐ones were obtained by direct nitration of the corresponding mono‐ or di‐substituted 5‐phenyl‐1,4‐benzodiazepines. Substituent effects and the orientation of aromatic substituents in the nitration products are discussed. The single‐crystal X‐ray structural data for one of these products, 18, is given.
