By using a simple copper(I) catalyst a high yielding sulfonylative-Suzuki-Miyaura cross-coupling reaction was developed. The process provided a single step route to diaryl sulfones from the direct combination of arylboronic acids, sulfur dioxide and aryl iodides, and represents the first sulfonylative variant of a classic cross-coupling reaction. Sulfur dioxide was delivered from the surrogate reagent, DABSO. Variation of the reaction conditions allowed interruption of the sulfonylative-Suzuki coupling, resulted in the formation of a presumed Cu-sulfinate intermediate. These sulfinates was trapped as their sodium salts and treated with electrophiles to allow access to arylalkyl sulfones, β-hydroxyl sulfones, sulfonamides and sulfonyl fluorides.
