Transition metal chemistry in ionic liquids

Transition metal chemistry in ionic liquids has increased dramatically in the last few years. Ionic liquids can be used to prepare transition metal complexes and clusters. They can be used to carry out stoichiometric reactions on ligands attached to transition metal ions, and they can also be used to support transition metal catalysts. Ionic liquids composed of organic cations and transition metal anions are also known. Each of these areas will be discussed in this article.
