What Is Metal Formwork?

Template reaction ^{[1] When} synthesizing a macrocyclic coordination compound, in the process of synthesizing an organic macrocyclic ligand, it is necessary to suppress a side reaction that generates a chain polymer at the stage of a ring closure reaction. The presence of metal ions facilitates macrocyclic synthesis. The added metal ion is usually called a template (or templating agent), and the radius of the template must be able to match the size of the pores of the large ring. Use a certain kind of cation that has a radius (usually a metal cation) that matches the cavity and human of the macrocyclic ligand molecule to be synthesized, and add the cation to synthesize the macrocyclic ligand in order to synthesize The reactions that are conducive to ring closure in the process are called template reactions. The role of the template in the synthesis process is called the template effect. It is the effect of the coordination of a ligand with a metal ion to change its electronic state and achieve a certain spatial configuration. Template reactions are divided into: thermodynamic template reactions, kinetic template reactions and equilibrium template reactions.
