tetradecahydro, octahydro, and dihydro-dibenzoheptazethrenes II, III, and IV respectively. The same hydrocarbons were obtained from the isomeric diketone V, involving a rearrangement. Dehydrogenation of the hydro derivatives or pyrolyses of the diketones in presence of copper powder gave the green dibenzoheptazethrene VI. This is a strongly basic hydrocarbon and forms stable salts VII. Oxidation formed the quinone
