A very efficient synthesis of (difluoroiodo)toluene avoiding the use of elemental chlorine and elemental fluorine is described. We have fluorinated a series of α-acceptor substituted selenides using (difluoroiodo)toluene.The reactions are usually very clean and under the reaction conditions no further oxidized products are observed.
Fluoride ion promoted anodic substitutions of chalcogeno compounds.2. Regioselective anodic methoxylation of 1,1-dihydro-perfluoroalkyl and cyanomethyl selenides.
