Abstract : A sulfonylative Hiyama cross-coupling reaction using gaseous SO$_2$ is described, using Pd-catalysts. The use of silicon-based nucleophiles leads to the formation of allyl sulfones under mild conditions with a broad functional group tolerance. Control experiments coupled with DFT calculations shed light on the key steps of the reaction mechanism, revealing the crucial role of a transient sulfinate anion.
