Click chemistry

Click chemistry is an approach to chemical synthesis that is used to join two molecules. The application of the term, click, as a qualifier to the type of chemistry refers to an emphasis on efficiency and simplicity. To link two molecular components, each is first fitted with appropriate functional groups, such as azide and alkyne groups. These components are then "clicked" together in a process that is highly favorable and which tolerates many functional groups that might complicate other coupling processes.
