Two fluorine atoms are effectively introduced to the 3- and 4-positions of sulfur-containing lactams through the action of the hypervalent iodoarene reagent difluoroiodotoluene (DFIT). The reaction proceeds through the intermediacy of the isolable alpha-beta -unsaturated congener followed by an additive-Pummerer process. (C) 2001 Elsevier Science Ltd. All rights reserved.
