Andrew J. Peel investigated efficient metalation of unfunctionalized aromatic compounds using mixed copper–lithium amide aggregates. The work connected aggregate composition with exchange behaviour, illustrating why an organometallic reagent's structure in solution can matter to its reactivity.[ref]

Metalation introduces a metal into a molecule or replaces an attached atom or group with a metal-containing connection. In organometallic chemistry, the term often refers to forming a carbon–metal chemical bond, for example by replacing a carbon-bound hydrogen.
The word describes the transformation, while the mechanism can involve proton transfer, metal insertion or other pathways. A metalated carbon centre may act as a nucleophile in a subsequent bond-forming reaction. Which site is metalated depends on acidity, coordination and kinetics, so the most acidic isolated bond need not uniquely predict the product under every reaction condition.
