The Stille Reaction is a chemical reaction that allows for the coupling of organotin compounds with organic halides to form carbon-carbon bonds. This reaction is particularly useful in organic synthesis, as it enables the creation of complex molecules from simpler ones. It typically requires a palladium catalyst and is valued for its ability to work with a variety of substrates. In the Stille Reaction, the organotin reagent reacts with an organic halide, leading to the formation of a new carbon-carbon bond. The reaction proceeds through a series of steps, including oxidative addition, transmetalation, and reductive elimination. This method is widely used in the synthesis of pharmaceuticals, agrochemicals, and advanced materials.
