named reaction

A name reaction is a chemical reaction named after its discoverers or developers. Well known examples include the Wittig reaction, the Claisen condensation, the Friedel-Crafts acylation, and the Diels-Alder reaction. Among the tens of thousands of organic reactions that are known, hundreds of such reactions are well-known enough to be named after people. Books have been published devoted exclusively to name reactions; the Merck Index, a chemical encyclopedia, also includes an appendix on name reactions.
