Organometallic Reactions Part 5: Nucleophilic/Electrophilic Attack on Ligands
Reactions that occur on the ligands themselves are quite common. Let's look at two common types of ligand reactions: nucleophilic and electrophilic attacks. Which types of ligands that are susceptible to these attacks and what happens?
