Nanomaterials have revolutionized various scientific and industrial domains due to their exceptional properties and diverse applications. Yet, challenges persist in achieving their controlled synthesis, stability, and recyclability, especially in catalysis. Organoselenium compounds are emerging as promising agents for the stabilization of nanomaterials, with high prospects for catalytic applications. This article covers the recent strides made in harnessing the potential of organoselenium compounds to stabilize diverse nanomaterials with applications in catalysis. Specifically, it delves into their effectiveness in Suzuki‐Miyaura cross‐coupling, C−O coupling, Sonogashira coupling, reduction of nitroarenes, synthesis of primary amides (in aqueous medium), and offers a comprehensive overview of this evolving field.
