Ligandpromoted
Ligandpromoted refers to a chemical process where the presence of a ligand significantly influences or enables a reaction. Ligands are molecules or ions that bind to a central metal atom to form a coordination complex. In catalysis, ligands play a crucial role by coordinating to a metal center, altering its electronic and steric properties. This modification can enhance the reactivity, selectivity, and stability of the catalyst, thereby promoting a desired chemical transformation.
The promotion effect of a ligand can manifest in several ways. It might stabilize reactive intermediates, facilitate
Common examples of ligandpromoted reactions include cross-coupling reactions like Suzuki, Heck, and Sonogashira couplings, which are
