Coupling reactions are chemical processes where two molecules are joined together, often forming a new bond. These reactions are commonly used in organic chemistry to create complex molecules from simpler ones. A well-known example is the Suzuki coupling, which involves the reaction of an organoboron compound with an organic halide in the presence of a catalyst. These reactions are essential in the synthesis of pharmaceuticals, agrochemicals, and materials science. By enabling the formation of carbon-carbon bonds, coupling reactions allow chemists to construct diverse and intricate molecular architectures, facilitating advancements in various fields of research and industry.
