Sorry, no etymologies found.
An early project returned me to my interest in cyclobutadiene and we designed a mechanistic study to determine if cyclobutadiene was really formed from the decomposition of the Pettit iron tricarbonyl complexes.
For my graduate work, I initially chose a project related to the Pettit work and finished studying the anti-aromaticity of cyclobutadiene.
Thus he achieved the first synthesis of cyclo-octatetraene, and went on to compare it with benzene; so also he set up experiments to produce cyclobutadiene.
