abstract
The effect of benzo and benzocyclobutadieno annelation on the current density induced in a series of biphenylene deriva- tives is examined at the B3LYP/cc-pVDZ level of theory, by using the CTOCD-DZ method. Angular benzo annelation in- creases, whereas linear benzo annelation decreases the intensi- ty of paratropic (antiaromatic) current density along the four-membered ring of biphenylene. The opposite effect is found for benzocyclobutadieno annelation. It is shown that the extent of local aromaticity of the four-membered ring in biphe- nylene congeners can vary from highly antiaromatic to nonaro- matic, as a result of different modes of annelation.
