Direct one step preparation and 13C-NMR spectroscopic characterization of a-ferrocenyl carbocations derived from ferrocene and carbonyl compounds in trifluoroacetic acid medium1a
Reaction of aldehydes and ketones with ferrocene, in the presence of trifluoroacetic acid, afforded a series of stable long lived alpha-ferrocenylalkyl carbocations which were characterized by 13C-NMR spectroscopy. When this reaction was attempted using tetraphenylcyclopentadienone, quite unexpected...
