Transmetalation is a term used in organic chemistry to describe the exchange of a ligand between two metal complexes. Synonyms for transmetalation include ligand exchange, metal-ligand interchange, and metal-ligand transfer. Transmetalation reactions are often used in the synthesis of complex organic molecules and are important in the production of OLEDs and other electronic devices. Other related terms include transamination, which is the transfer of an amino group between molecules, and transmethylation, which is the transfer of a methyl group between molecules. Understanding these terms and their applications is essential for students and practitioners in the field of organic chemistry.
