Desulfonative pd-catalyzed coupling of aryl trifluoroborates with arylsulfonyl chlorides

A Pd-catalyzed cross-coupling of aryl trifluoroborates with arylsulfonyl chlorides has been successfully achieved. This transformation is a new method for the Suzuki–Miyaura-type reaction of aryl trifluoroborates via the cleavage of C S bond, thus providing an alternative synthesis of biaryls. The reported cross-coupling reactions are tolerant to many common functional groups regardless of electron-donating or electron-withdrawing nature, making these transformations attractive alternatives to the traditional Suzuki–Miyaura coupling approaches.
