DIAZABICYCLOALKANES WITH NITROGEN ATOMS IN THE NODAL POSITIONS. 6. SYNTHESIS AND SOME PROPERTIES OF BENZO-1,5-DIAZABICYCLONONENE AND BENZO-1,6-DIAZABICYCLODECENE

Article abstract of DOI:10.1007/BF00506465

The reaction of N-acetyl derivatives of N,N'-trimethylene- and N,N'-tetramethylene-o-phenylenediamines with ethylene oxide gave the corresponding N-(β-hydroxyethyl)-N'-acetyl derivatives, the cyclization of wich in refluxing hydrobromic acid leads to benzo-1,5-diazabicyclo<3.2.2>nonene and benzo-1,6-diazabicyclo<4.2.2>decene.
