Therefore, numérous methodologies have been developed for their preparation. [1] However, the most common methods suffer from significant limitations with harsh reaction conditions or regioselectivity issues. Recently, the insertion of a molecule of sulfur dioxide between two partners was investigated and reactions involving organomagnesium,[2a] organozind2b] and organoboron[2c] compounds were reported. Herein we report a direct single-step palladium-catalyzed synthesis of sulfones involving organosilanes, sulfur dioxide and organohalides. Different mechanistic pathways were envisaged and discussed both from an experimental and theoretical stand point. %G English %2 https://cea.hal.science/cea-02329659/document %2 https://cea.hal.science/cea-02329659/file/Adenot_Gecom2019.pdf %L cea-02329659 %U https://cea.hal.science/cea-02329659 %~ CEA %~ CNRS %~ PUBNIMBE %~ DSV %~ INC-CNRS %~ IRAMIS-NIMBE %~ CEA-UPSAY %~ UNIV-PARIS-SACLAY %~ CEA-UPSAY-SACLAY %~ CEA-DRF %~ TEST-HALCNRS %~ GS-ENGINEERING %~ IRAMIS %~ GS-CHIMIE %~ GS-PHYSIQUE %~ INSTITUT-SCIENCES-LUMIERE %~ TEST2-HALCNRS
