A palladium‐catalyzed domino Heck/silylation reaction of acrylamides with hexamethyldisilane is presented. This transformation, which involves the formation of a σ‐alkylpalladium intermediate, allows direct access to functionalized (2‐oxoindolin‐3‐yl)methylsilanes in good to excellent yields. Furthermore, this strategy could be utilized for the synthesis of (2‐oxoindolin‐3‐yl)methylstannanes from hexamethyldistannane.
