Extract

The synthesis of 3-bromofluorenone is described and attention drawn to erroneous statements by previous workers in the field. The reduction of the ketone to 3-bromofluorene has been investigated and shown to be readily effected by heating with hydrazine hydrate in diethylene glycol. This appears to be the method of choice for reducing fluorenones to fluorenes.
