C–C Coupling Reactions

C–C coupling reactions are processes in chemistry where two carbon atoms from different molecules are joined together to form a new carbon-carbon bond. This is fundamental in building complex organic compounds, such as pharmaceuticals, plastics, and other materials. The reactions typically involve a catalyst—often a metal like palladium—that helps facilitate this bond formation efficiently and selectively. By linking these carbon atoms, chemists can create larger, more complex molecules from simpler ones, enabling the synthesis of diverse chemical products important in industry and research.
