(Fluorenone)tricarbonylchromium has been prepared in up to 46percent yield from (fluorene)tricarbonylchromium by two electrochemical methods whose key step is the formation of the (fluorenyl)tricarbonylchromium anion which reacts further with oxygen.The first method takes advantage of the basic properties of the superoxide anion, generated electrochemically in aprotic media; this anion is able to abstract a proton from (fluorene)tricarbonylchromium.In the second method, (fluorene)tricarbonylchromium is reduced to its anion in an inert atmosphere, prior to the introduction of oxygen.
