What is the roll of legand in Suzuki coupling reaction?

Question

Accepted Answer

The role of a ligand in Suzuki coupling reaction is to facilitate the formation of a stable complex between the catalyst and the reactants.

A ligand coordinates with the catalyst metal center, enhancing its reactivity and selectivity.
It helps in stabilizing the transition state and lowering the activation energy of the reaction.
Different ligands can influence the reaction rate and product distribution.
Common ligands used in Suzuki coupling include phosphines, phosphites, and N-heterocyclic carbenes.
For example, the use of bulky ligands can improve the regioselectivity of the reaction.

Accepted Answer

The role of ligand in Palladium catlysed coupling reactions like Suzuki coupling reaction is: ligand like Phosphine ligand increases the electron density at the metal center of the complex and therefore helps in the oxidative addition step.
