Abstract: The crystal structure of the addition product of p-quinonebenzenesulfonimide and diphenyldiazomethane, C₃₁H₂₄N₂O₄S₂, confirms earlier spectroscopic evidence that it is not a substituted benzocyclopropene, as previously claimed, but contains instead a bicyclic three-membered ring fused to a six-membered ring incorporating only one double bond.
