A　new　approach　to　the　synthesis　of　fluorinated　biaryl　compounds　from　easily　available　starting　materials　is　described.　This　protocol　is　based　on　the　direct　palladium-catalyzed　desulfitative　cross-coupling　of　polyfluoroarenes　with　various　arylsulfinate　salts　via　C-H　bond　activation,　accelerated　by　trace　amount　of　water.　The　method　allows　the　synthesis　of　various　fluorinated　biaryl　products　in　moderate　to　good　yields,　and　tolerated　a　variety　of　functional　groups,　including　alkyl,　phenyl,　methoxy,　fluoro,　and　chloro　groups.　(C)　2014　Elsevier　B.V.　All　rights　reserved.
