The thesis states that only three different methods were tried in the attempts to free C18 from the cobalt atoms; apparently, no model
systems were investigated.

Calculations performed at the ab initio HF/6-31G(d) level using

We have recently prepared the first examples of triyne- and tetraynelinked
dehydrobenzoannulenes. These systems, however, are relatively strain-free:
