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 autoxidation of sulphide ion to form the disulphide 6. An intramolecular autoxidation of the dianion 8 derived from 6 was expected to afford a 1,2-dithietane derivative 9 which eliminated sulphur to give bifluorenylidene 1. © 1995 Elsevier Science Ltd.
