Synthesis of Simple Monocyclic 1,3-Diazepines from 1,2-Diazepines
Thermolysis of the 1H-1,2-diazepines having an electron-donating substituent in the 4- or 6-position affords the corresponding 1,3-diazepines, whereas 1,2-diazepines having electron-withdrawing substituents do not show this ring-conversion.
