Herein, we report the magnetically recoverable Fe 3 O 4 nanoparticle‐catalyzed synthesis of 2‐organochalcogen‐benzothiazoles via direct C−H bond chalcogenation. This new approach works under an air atmosphere, affording the desired products in good to excellent yields using benzothiazoles, a half‐molar equiv. of various diorganyl dichalcogenides, and 10 mol % of catalytic loading. The method is attractive due to the recyclability of the catalyst and tolerance of a wide range of functional groups.
