Cyclacenes having mono boron or nitrogen atom in the backbone - a theoretical study

Türker, Burhan Lemi
Gumus, S
Semi-empirical molecular orbital treatment at the level of AMI unrestricted Hartree-Fock type calculations was performed on the Huckel type boron and nitrogen substituted cyclacenes. Substitution is done either in a peri position or a fusion points. Boron substitution is found to be destabilizing. whereas nitrogen substitution has stabilizing effect on parent cyclacenes.
