—Chemists Make Elusive Multifluorinated Ferrocene “Pentafluoroferrocene is only the second fluorinated ferrocene reported—and the most fluorinated reported” Ferrocene, the iconic sandwich-shaped metal complex, is the compound that made researchers hungry to explore organometallic chemistry. Chemists have prepared countless derivatives by modifying ferrocene’s two cyclopentadiene rings. But fluorinated ferrocenes have proven elusive, a frustrating situation given the importance of fluorinated hydrocarbons in catalysis. Chemists in Germany have now made 1,2,3,4,5-pentafluoroferrocene, which is only the second fluorinated ferrocene reported, after monofluoroferrocene in 1971 (J. Am.
