Abstract: Bifluorenylidene 1 was formed quantitatively when 9-mercaptofluorene 3 was treated with base and exposed to air. The initial step was established to be an intermolecular autoxication of sulphide ion to form the disulphide 6. An intramolecular autoxication of the dianion 8 derived from 6 was expected to afford a 1,2-diethietane derivative 9 which eliminated sulphur to give bifluorenylidene 1.
