method to access sulfones from aryl halides and sodium alkylsulfinates in the presence of CuCl is reported. Regio- and chemoselectivity for the sulfonylation is observed for polyhalogenated arenes. Mechanistic studies indicate that a copper sulfinate reagent is formed in situ from CuCl and sodium sulfinate based on NMR experiments. Potential reaction intermediates, including excited state aryl halides
