Used as a catalyst in organic synthesis, particularly in alkylation and coupling reactions. Exhibits good thermal stability and selectivity in transformation processes involving carbon–carbon bond formation. Applied in the preparation of fine chemicals and pharmaceutical intermediates where heavy metal catalysts are required. Shows utility in polymerization reactions, enhancing reaction rates and yields under mild conditions. Its bulky aryl groups contribute to reduced toxicity compared to other bismuth derivatives, making it suitable for lab-scale and specialized industrial applications.
