In the presence of a small amount of sodium methylate, cyclohexanone and benzil form an addition product, which is a "semicyclic" 1:4-diketone. No derivatives of a bicyclic cyclo-heptane were found. Its most conspicuous chemical property is its sensitivity to mineral acids; among the reaction products is found a diphenyltetrahydrocumarone. Although the addition product exhibits the phenomenon of halochromism, the existence of a perchlorate is doubtful, and it did not form a free radical.

It is shown that heat in the absence of a solvent converts the title compound into benzo[k,l]thioxanthen 7,7-dioxide, 7-thiabenzo[c]fluorene, and o-(1-naphthyl)-benzenesulphonic acid. From these results and a consideration of the related pyrolyses of the 3,10- and 1,8-dimethyl derivatives of the title compound, a free-radical rearrangement mechanism is proposed to explain the observations.
