Multi-component reaction



In chemistry, a multi-component reaction (or MCR) is a chemical reaction where three or more compounds react to form a single product.[1]

Examples of three component reactions:

Examples of four component reactions:

The exact nature of this type of reaction is often difficult to assess, in collision theory a simultaneous interaction of 3 or more different molecules is less likely resulting in a low reaction rate. These reactions are more likely to involve a series of bimolecular reactions.

New MCR's are found by building a chemical library from combinatorial chemistry or by combining existing MCR's.[2] For example, a 7-component MCR results from combining the Ugi reaction with the Asinger reaction.[3] MCR's are an important tool in new drug discovery.
