This organotin compound serves as a reagent in organic synthesis, particularly in palladium-catalyzed cross-coupling reactions such as the Stille coupling, where it transfers the 2-methylprop-2-enyl (methallyl) group to form new carbon-carbon bonds. It is essential for constructing complex molecular architectures in the synthesis of pharmaceuticals, natural products, agrochemicals, and advanced materials. Additionally, it finds use in allylation reactions and as an intermediate for preparing other organotin derivatives, which have applications in catalysis and polymer stabilization, including PVC additives.
