Abstract
CuI-catalysed cross-coupling reactions of various aryltrifluoroborates with aryl sulfinic salts have been achieved in good yields. A new efficient method is described for the conversion of potassium aryltrifluoroborates into diaryl sulfones. The reported reactions are tolerant to common functional groups regardless of whether they are electron-rich or electron-deficient, making this transformation an attractive alternative to traditional approaches.
