Abstract
The complexation of fluorenone by various Lewis acid triflates has been investigated in the ionic liquid 1-butyl-1-methylpyrrolidinium trifluoromethansulfonate (BMPY TfO). Addition of Yb(TfO)3, La(TfO)3, and Sc(TfO)3 produce an approximately 400 mV positive potential shift in the initial fluorenone reduction process. This process occurs as two merged peaks, probably due to fluorenone complexes having varying numbers of triflate ligands. By contrast, Hf(TfO)4 produces a single reduction peak shifted by +1.0 V from uncomplexed fluorenone.
