Synthesis of Azepine- or Azocine-Embedded Hexabenzocoronene-Based Nanographenes
Synlett, 2021AbstractClassical polycyclic aromatic hydrocarbons (PAHs) are a large group of π-conjugated planar structures. To explore more properties of PAHs, new structures have been designed, including some with nonplanar topologies and heteroatom-containing moieties.

Über Dibenz[b,f]‐azocin‐Derivate
Helvetica Chimica Acta, 1966AbstractAus o‐Aminodibenzyl (I) und o‐Amino‐cis‐stilben (IV) wurden mit Phosgen die Isocyanate II bzw. VIII hergestellt. Diese wurden als Harnstoffe V bzw. VII charakterisiert. Mit AlCl3 in Dichlorbenzol behandelt, ging II in das Azocin III über, während aus VIII das Indolon IX entstand.

Synthesis and properties of novel dibenz[b,f]azocines
Chemistry of Heterocyclic Compounds, 19915-Acetyl- and 5-trifluoroacetyl-12-hydroxy-11-cyano-5,6-dihydrodibenz[b,f]azocines have been synthesized by intramolecular cyclocondensation of ethyl N-acetyl and N-trifluoroacetyl-N-[1-(cyanomethyl)benzyl]-anthranilates. Spectral data show that the hydroxyl group in 5-acetyl-12-hydroxy-11-cyano-5,6-dihydrodibenz[b,f]azocine takes part in transannular ...
