Treatment of alpha-phenylsulfanyl esters 11-14 with one equivalent of difluoroiodotoluene 3a produced the alpha-fluoro sulfides 17-20 in good overall yield through a Fluoro-Pummerer reaction. A second equivalent of reagent produced alpha,alpha-difluoro sulfides and a third led to alpha,alpha-difluoro sulfoxides. An identical pattern of reactivity was observed with the alpha-phenylsulfanyl lactone 26. This sequential fluorination-oxidation behaviour was exploited in the one-pot synthesis of 3-fluoro-2(5H)-furanone 33 starting from alpha-phenylsulfanylbutyrolactone 32.
