Methodologies for the introduction of fluorine functionalities into organic
molecules by electrochemical oxidation and reduction, which consist of red
uctive monodefluorination of trifluoromethyl imines and ketones to difluoro
enamines and enol silyl ethers, oxidative bond formation between amino-nitr
ogen and aromatic ring carbon leading to 2-trifluoromethylbenzimidazoles, f
luoro-selenenylation of olefins by recycling active selenenylating reagents
, perfluoroalkylselenenylation of olefins via indirect electron transfer, a
nd electrochemical trifluoromethylation, are described.
