Studies on the oxidation and fluorination of α-phenylsulfanylacetamides using difluoroiodotoluene

alpha-Phenylsulfanylacetamides are fluorinated in the alpha-position when treated with difluoroiodotoluene (DFIT) in a fluoro-Pummerer reaction. For N-phenyl amides an intramolecular Friedel-Crafts reaction may compete and produce heterocycles. (C) 2000 Elsevier Science Ltd. All rights reserved.
