An efficient palladium-catalyzed reductive cross-coupling of propargyl acetates with aryl iodides involving the insertion of sulfur dioxide has been reported. This method employs 1,4-diazoniabicyclo[2.2.2]octane-1,4-disulfinate (DABSO) as SO2 surrogate, reductive manganese powder as reductant, and features mild reaction conditions, broad substrate scope and good functional group tolerance.

Key words: palladium-catalysis, reductive cross-coupling, propargyl acetates, sulfur dioxide
